CCTV News:The Yangtze River is the mother river of the Chinese nation. Four years ago, General Secretary of the Supreme Leader pointed out at the symposium on promoting the development of the Yangtze River Economic Belt held in Chongqing that the Yangtze River has a unique ecosystem and is an important ecological treasure house in China. At present and for a long time to come, it is necessary to put the restoration of the ecological environment of the Yangtze River in an overwhelming position, work together for great protection and not engage in great development. How has the Yangtze River been managed since the Yangtze River Economic Belt was comprehensively promoted four years ago? How can we call back green mountains and green waters? Maanshan City, Anhui Province, was once a big polluter. What is the situation there now?

　　　　　　 In 2019, the Ministry of Ecology and Environment and Taiwan formed a joint investigation team to conduct unannounced visits to 11 provinces (cities) along the Yangtze River Economic Belt in eight months. The investigation found that the Yangtze River still faces three main problems: the total amount of pollution discharge is huge, the ecological damage is serious, and the risk of environmental pollution is still great.

　　　　　　 According to statistics, the total amount of wastewater received by the Yangtze River basin accounts for about one-third of the whole country every year, and the pollutant discharge per unit area is about twice the national average. The biological integrity index has reached the worst fish-free level; More than 400,000 chemical enterprises are densely distributed along the river, and a large number of solid wastes are piled up on the shore, which poses a greater risk of environmental pollution. In a word, the Yangtze River is still a river with high load, high pollution and high risk, and the environmental protection situation is still grim.

　　　　　　 Xing Changcheng, deputy director of the Second Inspector Department of the Central Eco-environmental Protection Inspector Office, said: "In some localities and departments, the ideological understanding of protecting the Yangtze River and the great protection of the Yangtze River is still not in place, and the implementation of the new development concept is still not in place, especially in some places, the phenomenon of seeking temporary economic development at the expense of eco-environmental protection still exists, and many similar problems have been found during our inspection."

　　　　　　 So how to deal with the relationship between economic development and environmental protection? Maanshan City, Anhui Province has made some explorations. Speaking of Ma ‘anshan, Maanshan and pollution may be the first thing that many people think of. In 1956, Ma ‘anshan was set up for steel, and changed from a small fishing village into a city of steel. Since then, it has been in the situation of "one steel dominates" and "one Mara city" for a long time. Later, many related industries were derived along the Yangtze River, which made Ma ‘anshan long-term "riverside not see the river, water is not hydrophilic".

　　　　　　 Xuejiawa is a depression near the Yangtze River. Two years ago, it was devastated, and it was the most prominent and typical place for environmental protection in Maanshan.

　　　　　　 At the end of 2017, Zhang Yuefeng, secretary of the municipal party committee, was interviewed by his superiors as soon as he took office because of pollution.

　　　　　　 Although I have no bottom in my heart, I have no way out. In Zhang Yuefeng’s view, the key to whether this thing can be done is to make up your mind. To solve the environmental problems in Ma ‘anshan, we must not only use environmental protection means, but also adjust the economic structure, upgrade backward industries and treat them from the source. Xuejiawa was regarded as a breakthrough. The pollution sources in Maanshan can be roughly divided into water, shore and city. On the shore where the problem is most concentrated, there are 153 illegal docks, 684 scattered pollution enterprises, 62 solid waste dumps and 497 farms. This was a stumbling block that was placed in front of the local government two years ago and must be dismantled or shut down according to law, but the resistance is great. Wanjiang Cement Plant located in Xuejiawa wants to stay on the riverside by completing the formalities.

　　　　　　 Zhang Yuefeng, secretary of Ma ‘anshan Municipal Party Committee, said: "I told him (the business owner) that it was impossible. I said that now not only I but also you must follow the general secretary’s requirements for the great protection of the Yangtze River. At that time, we said ‘ Four zeros ’ It is called zero tolerance in attitude, zero luck in thought, zero slack in action and zero tolerance in punishment. "

　　　　　　 Although some enterprises can’t shut down, they can greatly reduce pollution through upgrading. The refractory factory under Masteel is near Xuejiawa, only 2 kilometers away from the Yangtze River. Although it has made great contributions to Masteel, it is also a highly polluting enterprise and needs rectification.

　　　　　　 When Maanshan began to renovate along the Yangtze River, the refractory factory set up a new company with a listed company, invested 200 million yuan, moved into the industrial park, built new factories and used new equipment, and the pollution problem was completely solved.

　　　　　　 Maanshan Iron & Steel Refractory Factory did not close down because of environmental improvement, but took the opportunity of Yangtze River improvement to upgrade. According to this idea, Maanshan will either completely shut down other polluting enterprises along the Yangtze River, upgrade or transform into other low-pollution industries.

　　　　　　 In addition to polluting enterprises along the coast, water pollution sources are also one of the key points of remediation. Before the regulation, there were both past transport ships and more than 11,000 fishermen on the river. There were four or five hundred people and more than 200 boats in Xuejiawa alone. These fishermen have lived by fishing for generations, and as a result, they have almost no fish to catch because of pollution and overfishing. If we want to cure it, we must let these fishermen go ashore to retreat and change their production. But in the face of going ashore, the fishermen are on tenterhooks.

　　　　　　 In view of the fishermen’s greatest concern, the Maanshan government has put forward a "four haves and one free ride" scheme with jobs, housing, schooling, social security and a good mood, so as to reassure the fishermen.

　　　　　　 Due to proper measures, it only took more than two months, and Maanshan took the lead in completing the ban on fishing in the main stream and main tributaries of the Yangtze River and the fishermen’s retreat and conversion, one and a half years ahead of the national requirements. More than 5,100 fishing boats were dismantled and all 11,000 fishermen landed.

　　　　　　 Besides water and coastline, the third pollution source is urban domestic sewage. In the past, due to the backward urban planning and weak environmental awareness, rainwater and sewage in many old communities were mixed and discharged, which led to the pollution of the Yangtze River. This is a long-standing problem that has accumulated for decades. To achieve a radical cure, it is necessary to transform the city’s pipe network, which is equivalent to a major operation for the city. There are many difficulties. First of all, money is a hard bone.

　　　　　　 In order to solve the problems of capital, technology and management, Maanshan hired top domestic scientific research institutes to make plans, and also launched an "environmental butler" to seek breakthroughs by using third parties.

　　　　　　 After finding a way, Maanshan began to treat the rain and sewage pipe network and the rivers in the city from the source.

　　　　　　 After the rain and sewage are separated, the sewage is sent to the treatment plant for treatment, and the black and smelly sewage immediately turns into clear water and flows into the river. Therefore, the water quality of rivers in the city has improved significantly. Cihu River is the mother river of Maanshan. In the past, there were many black and odorous water bodies, but now it has changed a lot.

　　　　　　 In this way, Maanshan solved the pollution problems on water, coastline and city. Only when the environment is well managed can we introduce low-pollution high-tech industries, thus solving the problems of environmental protection and development from a higher level of adjusting the economic structure. Ma ‘anshan Zhengpugang Modern Industrial Park is a new park to develop high-end industries. When the reporter met the director Wu Xiaodong, the person in charge of the park, he had just returned from Shenzhen with Zhang Yuefeng, secretary of the municipal party committee.

　　　　　　 Wu Xiaodong, secretary and director of the Party Working Committee of Zhengpugang Modern Industrial Park in Maanshan, said: "All highly polluting enterprises will not enter, and all industries will be oriented, mainly high-end manufacturing, electronic information industry and green food, as well as port logistics relying on ports."

　　　　　　 After years of construction, a number of advanced high-end manufacturing enterprises and research institutes have settled in the modern industrial park of Zhengpugang New District.

　　　　　　 Environmental protection and economic development are no longer a pair of contradictions in Maanshan, but partners that promote each other. In the first three quarters of 2019, the city’s GDP reached more than 150 billion yuan, an increase of more than 20% over the same period in 2017. In 2018, Maanshan City was re-recognized as a national health city. Xuejiawa has become a good place for people to relax.

　　　　　　 Xue Mingfei, deputy head of Yushan District, Maanshan City, Anhui Province, said: "There are more biodiversity than before, especially we can see finless porpoises here. In the past, we could not see finless porpoises on the river."

　　　　　　 It is urgent to control pollution and restore ecology. In the process of promoting the development of the Yangtze River Economic Belt, what we want to "break" is not the environment, but the thinking and practice of barbaric and disorderly development, and what we want to "establish" is "ecological priority and green development". "Pollution before treatment" is not a law of development, but a lesson of blood. From January 1, 2020, the fishing ban will be implemented in key waters of the Yangtze River basin by classification and stages, and at the latest from 0: 00 on January 1, 2021, the fishing ban will be implemented for a tentative period of 10 years in the natural waters of the main stream and important tributaries of the Yangtze River except for aquatic nature reserves and aquatic germplasm conservation zone. This is a responsible attitude and action towards history, the future and future generations.

　　Li Weiqing, who works in Beijing, didn’t pay much attention to the news that Spring Festival travel rush Railway will start selling tickets in 2020. Since buying a car, he has chosen to drive home every Spring Festival. He has been running for several years from Beijing to Jinzhou, Liaoning Province, about 500 kilometers of expressway.

　　"If it goes well, it will take five and a half hours. Once I caught a traffic jam, I got home in nine hours." In Li Weiqing’s view, driving home not only saves the anxiety of grabbing tickets, but also increases the opportunity to chat and talk with parents.

　　"Because I used to travel a lot in my previous job, it is actually a rare opportunity to communicate with my parents by car in the New Year. Starting from home, bring all the food and drink, and hurry and slow all the way. It is easier to talk and chat. " Li Wei qing said.

　　With the Spring Festival travel rush train ticket on sale on December 12th, "Spring Festival travel rush in 2020" once again boarded the hot search. Compared with Spring Festival travel rush in 2019, Spring Festival travel rush will be 11 days ahead of schedule in 2020. Therefore, some experts predict that Spring Festival travel rush will see the peak of passenger travel in the early stage, which is the superposition of "work flow", "student flow" and "visiting relatives flow", and "going home" has become a common keyword for many people who work and live outside the home.

　　Step on the accelerator to the end, and the congestion at the provincial border will be alleviated.

　　According to big data, during Spring Festival travel rush in 2019, the national railways, highways, waterways and civil aviation sent a total of 2.98 billion passengers, which was basically the same as that in 2018. Among them, the railway sent 410 million passengers, an increase of 7.4%; 2.46 billion passengers were sent by road, down by 0.8%; The waterway sent 41 million passengers, the same as in 2018; Civil aviation sent 73 million passengers, an increase of 12%.

　　In recent years, the trend of diversification of transportation modes in Spring Festival travel rush has become more and more obvious. Trains, planes, cars, hitchhiking and other ways go hand in hand, which has alleviated the pressure of passenger flow during Spring Festival travel rush to some extent. It is worth mentioning that with the increase of income and the update of travel concept, many people have joined the team of driving home.

　　According to the consulting data of Ai Media, 47.9% of the netizens surveyed indicated that their willingness to travel by car during Spring Festival travel rush in 2019 was significantly improved.

　　Some analysts believe that, on the one hand, according to the data of the Ministry of Transport, in 2018, the mileage of new highways in China was 86,000 kilometers, including 6,000 kilometers of expressways and 20,000 kilometers of newly built and rebuilt provincial trunk highways. The highway has been built to the "doorstep", which provides convenience for many self-driving families.

　　On the other hand, the number of motor vehicles in China continues to increase, and cars are becoming the standard of life for many people, which provides conditions for self-driving travel.

　　Ai Media Consulting analysts said that people’s living standards have improved and the number of private cars has been continuously improved. At the same time, the country has strengthened highway construction, and the trend of self-driving travel during the Spring Festival is obvious. The diversified combination of roads, railways and aviation has become the general direction of Spring Festival travel rush’s travel structure adjustment.

　　It is worth mentioning that traffic jams have always been one of the pain points of self-driving in Spring Festival travel rush, and high-speed toll stations are the "hardest hit areas" of congestion. In Spring Festival travel rush this year, this situation will improve.

　　On December 12th, the Ministry of Transport held a special press conference on "Cancellation of Provincial Toll Stations of Expressway". According to Sun Wenjian, spokesman of the Ministry of Transport, the project of canceling the provincial toll stations of expressways has entered the final stage, and the conditions for canceling the provincial toll stations of expressways nationwide are basically met before the end of the year.

　　Specifically, in terms of engineering construction, the completion rate of the national highway entrance weighing detection system has reached 100%. On December 16th, the national highway entrance weighing detection will be fully implemented. The completion rate of the main line reconstruction of provincial toll stations reached 93.02%, and the main line reconstruction of the remaining provincial toll stations was completed before December 20 as planned.

　　Sun Wenjian said that in ETC issuance, as of December 10, the total number of ETC customers nationwide reached 185.4599 million, completing 97.17% of the total issuance tasks; The network communication link test and system function test have been completed, and it is expected that all the work of joint debugging and testing will be completed before December 20.

　　It is understood that the cancellation of provincial toll stations on expressways is not a cancellation of charges, but a change in charging methods. At the same time of dismantling the provincial toll stations, it is helpful to reduce the transit time of vehicles by technical means to realize fast payment without stopping when driving across provinces.

　　"After the withdrawal of the station, under normal traffic conditions, the average time for buses to pass through the provincial boundary was reduced from 15 seconds to 2 seconds, a decrease of about 86.7%. The time for trucks to cross provincial boundaries was reduced from 29 seconds to 3 seconds, a decrease of 89.7%. " Sun Wenjian said, "After the provincial toll station of the expressway is cancelled, the people will be truly realized ‘ Step on the accelerator to the end ’ The dream of ".

　　Customized buses, hitchhiking and other new favorites "internet plus" empower Spring Festival travel rush to go home.

　　Although Spring Festival travel rush hasn’t officially started, Li Yong’s homecoming WeChat group is already full of excitement. "Between the 10th and 15th, did anyone return to Anhui via Wuxi, Changzhou and Nanjing?" "Looking for someone by train on the 20th, waiting for 2, waiting for 1" & hellip; … Working in Shanghai and his hometown in Huainan, Anhui Province, he continued to pay attention to the information in the group, hoping to get on a bus and go home.

　　In fact, carpooling home is becoming a new choice for more and more young people in Spring Festival travel rush.

　　Hellobike’s "Big Data on Travel in the Spring Festival of 2019" shows that during the Spring Festival of 2019, the average carpooling distance of Hello was 126.7 kilometers, the average carpooling time was 143.3 minutes, and the average carpooling cost was 122.6 yuan, so long-distance travel became the main order for hitchhiking.

　　Among them, the age of hitchhiking passengers is mainly between 24 and 32 years old, and the proportion of post-80 s and post-90 s is 41.1% and 44.9% respectively, and post-90 s becomes the main force of hitchhiking.

　　Li Yiming, who works in Beijing, is a hitchhiker. Online booking and telephone communication confirmed that during the Spring Festival last year, he took two passengers back to his hometown of Tangshan through a ride platform.

　　"The two passengers paid a total of more than 300 yuan and shared the fuel and tolls." Li Yiming said, "We also had lunch together at the high-speed service station on the way. It’s my treat, not for anything else. I just think it’s quite warm and I can have a chat companion along the way."

　　In fact, "internet plus" has brought many changes to Spring Festival travel rush. During the period of Spring Festival travel rush, in order to meet the diversified needs of tourists, customized buses began to enter the market in some places. By combining online and offline, and booking trips in various ways, the customized bus is based on highway passenger transport, which plays a role in connecting railway and air traffic in series.

　　Ding Yifan, who lives in Hangzhou, told reporters that during her stay in Spring Festival travel rush in 2019, she experienced a customized bus for the first time. On the arrival floor of hangzhou east railway station, find the dedicated service desk of "Spring Festival travel rush Warm Bus". As long as you register your destination, the service staff will match it in time, and "Spring Festival travel rush Warm Bus" will send passengers to the door of the community as far as possible.

　　"It has not only the routes in the city, but also the custom-made lines for returning home, the special shopping line for the Spring Festival, the bus lines connecting transportation hubs, etc., which saves the trouble of queuing at the train station and solves the last mile of Spring Festival travel rush." Ding Yifan said.

　　Scan code through the gate, brush your face into the station, and purchase tickets by electronic one-click … … In addition to hitchhiking and customized buses, the empowerment of "internet plus" makes the service in Spring Festival travel rush more intelligent, efficient and convenient, and constantly refreshes the travel experience of passengers. There is reason to believe that in the future, people will travel more and more, and the way home during the Spring Festival will be warmer.

Original title: The measured performance of the diskless system in Internet cafes is 60% worse than that of different systems under the same configuration.

　　[PConline gossip]After returning from the visit to Zhongshan, our PConline cafe visiting team has always had a doubt. How is the development of Internet cafes in a big city with more brutal competition and rapid changes? Will the development be more advanced? With these doubts, we were lucky enough to visit Bayou Internet Cafe and its owner, Mr. Ouyang, located in Gangding, Guangzhou. Next, the PConline Internet Cafe Visiting Team took everyone into Bayou Internet Cafe to uncover the secrets of all aspects of the Internet Cafe. In this issue, we will mainly continue the previous test of the diskless system in Internet cafes, and see what the difference is between it and the common system with the same computer.

This is the past content of our Internet cafe visit series. Interested friends can click on the portal below to watch!

[Secret of Internet Cafe You Don’t Know] No.4: The owner of Internet Cafe revealed himself: Why did I spend 1 million to modify water cooling?

　　Bayou Internet Cafe is located in Gangding, Tianhe District, Guangzhou. Gangding is a relatively prosperous area in Guangzhou. Digital enthusiasts who live in Guangzhou should know that Gangding is the "holy land" of computer hardware and digital accessories in Guangzhou, where Pacific Digital Plaza, Tianhe Computer City and Bainaohui are concentrated. When the PC industry was brilliant, it was once the most influential computer hardware store in South China. Nowadays, although consumers prefer to buy computer hardware online, it is still the most important place for Guangzhou people to buy computer hardware and digital products offline. In addition, there are Jinan University and South China Normal University around Gangding. As we all know, students are a very noteworthy consumer group, which also affects the business direction of Gangding, a local shop. Mr Ouyang and his partners started the Internet cafe business in this digital place.

　　The business style of offline shops has always been determined by the attributes of the consumer groups living nearby. Because of the geographical location, the target audience of Bayou Internet Cafe is the consumer groups with strong spending power and high requirements, such as nearby college students. Therefore, Bayou Internet Cafe attaches great importance to the design of the store environment. Mr. Ouyang revealed that although most consumers of Internet Cafes are for e-sports games, they also have different needs, so he divided the various areas of Internet Cafes.

　　The overall environment of Internet cafes will feel like a coffee shop, which is completely free from the dirty, chaotic and poor phenomenon of previous Internet cafes. Besides, smoking is also prohibited in Internet cafes, and the overall atmosphere is more comfortable and casual.

　　The front desk of the Internet cafe is a water bar. Mr. Ouyang revealed that 30~40% of the income of Internet cafes now comes from value-added services, which is also the biggest difference between Internet cafes and Internet cafes in operation.

　　Near the bar is a leisure and entertainment area, which is mainly equipped with an all-in-one machine and relatively cheap, but it is quite suitable for customers who like to play small games and surf the Internet.

　　The e-sports area is naturally the largest in the area, and it is full of computers configured for e-sports games, including Razer peripherals and HKC e-sports screens.

　　Recently, the rise of chicken-eating games has also made a lot of changes in Internet cafes. Bayou Internet Cafe has specially set up private rooms to bring friends to consumers to eat chicken in multiple rows.

　　There is a high platform in the e-sports area, which is a high-end configuration experience area. The configuration is GTX1080 and i7 6700K with full split water cooling blessing. There are six computers on one side and twelve computers on both sides, and there is a big screen live broadcast in the middle. It seems that the original intention of the design is to broadcast the LOL 5V5 game live, but now the consumption above is eating chicken, and the screen is also playing the anchor’s chicken-eating video.

　　The leisure and entertainment area on the other side is relatively small and fresh in decoration, with curtains on the seats to give consumers private space, which is very suitable for couples or friends to get together, chat, play games together and watch a small movie.

　　In addition, Bayou Internet Cafe also set up a mobile game area in a forward-looking way, which is also a test of Mr. Ouyang’s preference for consumer groups. After all, Internet cafes are positioned as a place for friends to meet, and now mobile games are hot, and everyone can get together to play mobile games. Can also achieve the purpose of the party.

　　Generally speaking, the atmosphere of Internet cafes makes people feel very comfortable. Dividing different sections can also adapt to the needs of various consumer groups, completely refreshing the cognition of Internet cafes in a winter. Next, we will continue the previous experiment to test the difference between the diskless system of Internet cafes and the computer performance of Internet cafes under our own system. In the third phase of our test of SO Hao Internet Cafe, we found that there is no difference in hard disk running scores between the two systems, but the diskless system will lead slightly in the number of game frames. Let’s see if it is the same in Bayou Internet Cafe.

　　Whole machine configuration:The computer host is in a small iron box under the game table, and there is no separate chassis, so the design is more integrated, and most people can’t find the existence of the host. In terms of computer hardware configuration, the core configuration is i5-6500+GTX 1060 3GB+16GB memory, which is a very balanced configuration. CPU, graphics card and memory will not be short boards, and they can basically play various 3A masterpieces smoothly. Next, let’s look at the differences between these hardware and our daily use one by one.

Memory:

　　In terms of memory, Bayou Internet Cafe uses Samsung DDR4 2100MHz general bar. We found this product in Taobao, and there are not many merchants selling it. It is estimated that it is mainly delivered by work packages, and its performance is quite satisfactory, but it is better than Samsung’s reputation of stable and reliable particles. Memory is more prone to problems in computer hardware, and internet cafes are taboo for computer instability, so it is reasonable to choose this memory stick.

Graphics card:

　　Bayou Internet Cafe uses GTX1060, which Internet Cafes prefer, but since Bayou Internet Cafe opened its doors for business the year before last, there was no GTX 1060 5G version at that time, so GTX 1060 3G version was adopted. From the picture, the specific model of the graphics card is Sotheby GTX 1060 3GB Destroyer. The performance of this graphics card can play most games smoothly, and the only shortcoming is the video memory. Many new games represented by eating chicken will occupy about 4GB of video memory even at 1080p resolution, but the video memory of this graphics card is just not enough, and playing some games will lead to the explosion of video memory.

Motherboard:

　　The motherboard uses ASUS EX-B150M-V3, and B150 motherboard and i5-6500 are considered as a cost-effective gold partner. As a first-line manufacturer, ASUS’s motherboard is also famous for its stability.

　　Next, we will be the same as before in Zhongshan.Test the performance of the original diskless system on the same machine and the performance after adding the Mingjue A6 Big Mac solid state (with win10 system) we brought. The graphics card drivers are NVIDIA 391.01.

　　CineBench R15 is a convincing CPU testing system. The Cinema 4D special effects software engine developed for the film and television industry is used to test a high-precision 3D scene rendered by CPU, which can support up to 256 logic cores. In addition, the new version also strengthens the investigation of shaders, anti-aliasing, shadows, lighting and reflection blur, and the detection of CPU performance is more accurate.

　　Summary:The test showed strange results. In our solid-state system, the CPU performance met the score of i5-6500, but it was obviously abnormal in the original diskless system, far from the normal level of i5-6500. Is it a software problem? Let’s keep testing.

　　CPU-Z is a well-known CPU detection software, and it is the most used software to detect CPU. Its own Benchmark can accurately judge the multi-core performance and single-core performance of CPU.

　　Test summary:In the CPU-Z test, the computer is still in an abnormal state under the diskless system. Is there something wrong with our CPU-Z software? I began to doubt life one winter.

　　X264 FHD Benchmark can effectively test the floating-point operation performance of CPU and the actual file-changing ability of multimedia audio and video.

　　Test summary:In the software for testing the actual ability of CPU, the performance of the computer under the diskless system is still poor, so it seems that it is not the software problem we brought.　　

　　Winrar is a commonly used compression/decompression software, and its own benchmark performance test can test the compression ability of a computer, which is similar to that of a computer.Processor performance and memory performanceIt matters.

　　Test summaryThe test results were still very embarrassing.

　　Fritz Chess Benchmark is a chess software, which can be used to test the computing performance of CPU.

　　Test summary:Chess is a software that simply measures the performance of CPU. It seems that the performance of i5 -6500 is obviously inhibited under this diskless system. Let’s see if other computer hardware will behave abnormally.

　　7-Zip is a completely free and open source compression software, and its own benchmark performance test can adhere to the decompression/compression ability of the computer, mainly measuringProcessor and memoryPerformance.

　　Test summary:The decompression performance is basically the same, but the compression performance of diskless system is still almost the same, but it basically belongs to the same performance.

　　AIDA64 is a tool for testing software and hardware system information, which can display every aspect of PC information in detail. AIDA64 not only provides many functions such as assisting overclocking, hardware debugging, stress testing and sensor monitoring, but also can comprehensively evaluate the performance of processor, system memory and disk drive..

　　Test summary:In terms of memory performance, this diskless system is much worse than the memory writing performance.

　　3Dmark is a software specially designed for measuring the performance of graphics cards by futuremark Company, and it has released 3Dmark99, 3Dmark2001, 3Dmark2003, 3Dmark2005, 3Dmark2006, 3Dmark vantage, 3Dmark 11 and The new 3DMark. Now, 3Dmark is not only a software to measure the performance of graphics cards, but has gradually turned into a software to measure the performance of the whole machine. 3DMark’s test physical score can be basically calculated.Actual game performance of CPU.

　　Test summary:From the test point of view, the graphics card performance of the platform is no problem, and the problem still appears on the CPU. This is the case under the running software, so how does it perform in the game?

　　Test summaryThe game "Survival of the Jedi" needs no introduction for a winter. I believe everyone is very familiar with it. In the test, we used the same DEMOS. Under the diskless system in the Internet cafe, the machine ran 46 frames, which was nearly 30 frames less than using our own system. Assuming that the performance under the diskless system is 100%, then the performance of the machine game has soared by 60% under SSD. How on earth is this fat?

　　What is behind this huge performance gap?Distortion of human nature or moral decayWhat’s the reason? After our conversation with Mr. Ouyang, we infer that there are several reasons. Let’s start with the startup principle and mechanism of the diskless system.

　　First, the network card of a diskless workstation is equipped with a Boot ROM. When the workstation is started by LAN, it will send a boot request signal to the server. When the server receives the signal, it will send boot data to the workstation according to different mechanisms. After the workstation downloads the boot data, the system control will be controlled by the Boot ROM.Go to some areas of memory.. That is to say, the diskless system will occupy part of the memory, SO whether it’s SO Hao Internet Cafe in Zhongshan or Bayou Internet Cafe in Guangzhou, they will give priority to ensuring that the memory is 16GB, and I believe other Internet cafes using diskless systems are also the same. And the memory is occupied, so it is understandable that the memory reading and writing performance will be affected to some extent.

Internet cafe system desktop

　　Second, when we communicated with Mr. Ouyang, we learned that the system of Internet cafes needs to meet the needs of consumers such as ordering food, calling service, charging and timing, so there are many programs hanging in the background, which leads to a certain degree of influence on the CPU performance of computers. However, the system of Soho Internet Cafe that we visited in the past did not have these humanized functions, which is related to the fact that the business direction of Soho Internet Cafe is more inclined to the positioning of traditional Internet Cafe, which mainly relies on network fees, while the positioning of Bayou Internet Cafe is more inclined to "coffee", and the user experience such as environment and good value-added services is more important, SO the system of Soho Internet Cafe is relatively streamlined, and it is even a little faster to run games in our previous tests.

　　The third reason is that the performance of disk reading and writing may encounter a bottleneck. The Internet cafe machine is divided into two parts: server and client. Under the diskless system, the client does not need to be equipped with a hard disk. All clients connect to the super-large hard disk in the server through the network and start it by using the system image in the hard disk. The files in the server hard disk can be read by all clients. If they are connected,Wire, network bandwidthIf it is not enough, it may cause data reading and writing to get stuck.

　　At present, most mature Internet cafes have a mature diskless system provider. When choosing a diskless system, Internet cafes will think and choose according to their business orientation. However, the difference in computer performance between customized systems is beyond our expectation. Therefore, PConline suggests that Internet cafe operators should check whether the diskless system has a great impact on hardware performance when choosing a diskless system provider. For example, the diskless system we evaluated this time has a great inhibition on computer performance, and it is a pity that the computer only played its original performance of 60%.
