Why doesn’t the computer in the Internet cafe get stuck？ You can’t even think of the reason!

　　[PConline gossip]I believe that many netizens who have been to Internet cafes will have a kind of doubt. Why can computers in Internet cafes open games and files so smoothly? Playing games can be so cool? And the computer at home is stuck and slow? So many netizens continue to habitually go to Internet cafes to play games. After all, good experience is king. As it happens, a few days ago, PConline interviewed many owners of Internet cafes. Today, we will uncover the secret of why the computers in Internet cafes are so fast.

　
The author’s computer configuration for a winter office.

　　Most internet cafes have higher hardware configuration, and the configuration is assembled for playing games, while most netizens’ computers at home may only be relatively rudimentary configuration, which can only meet the needs of daily light office entertainment, audio and video. We visited and found that,Nowadays, the mainstream configuration of Internet cafes is the sixth generation version of i5+GTX 1060 3G.And the high-end configuration of Internet cafes can go to the 6th generation i7+GTX1070, and the newly installed Internet cafes may also have GTX 1060 5G version. Even the mainstream configuration of internet cafes is higher than that of many netizens’ home computers. Spending money can make you stronger, the computer configuration of internet cafes is higher, and the experience will naturally be better.

　　Memory refers to memory storage, which is mainly used to temporarily store data. It is equivalent to a bridge, which is used to exchange data between hardware such as hard disk, motherboard and graphics card and the processor.We can think of memory as a data cache, a high-speed cache..When we use computers, computersWill guess the data you often use and store it in memory, and the data exchange speed between processor and memory is much higher than that between processor and hard disk, so it is very important to have enough memory for computer use.In this way, the computer can guess that you often use more data and store it in memory. For example, when we play the game of eating chicken, a large amount of data often used in the game operation will be stored in the memory. If your memory capacity is not enough and some commonly used data in the game operation can’t be put in, then the CPU can only exchange data with the hard disk at this time, which will cause a sense of stagnation and delay. We have tested that eating chicken requires 8GB or more of memory, and many computers in our home may still stay at the stage of 4GB of memory, so it is not unexpected to play with chicken. In addition, the choice of memory also involves a concept of single and dual channels.

　　The so-called single-channel memory is put forward relative to the concept of dual-channel memory. Simply speaking, a computer has only one memory.Single-lane memory can only read or write at the same time. Only one car can pass through a single lane, and only one car can enter or exit at the same time. It doesn’t matter when there is little traffic, but when there are many cars, they wait for each other. Dual-channel memory means that different channels are used for memory reading and writing, which can be read and written at the same time, and the memory bandwidth is doubled. Just like a two-lane car, it goes in and out at the same time and does not affect each other.

　　More than 90% of our home computers use single-channel memory. On the one hand, the memory is too expensive, on the other hand, many computer manufacturers think it is unnecessary, and one more part will lead to one more after-sales risk. After our investigation, we found that all the memory of the Internet cafes we visited was 16GB, and it was dual-channel, so the memory of the computers in the Internet cafes would not become a bottleneck for reading and writing, and the experience was good.

　　A very important reason that affects the experience is of course the internet speed, and Internet cafes all have dedicated optical fibers, so it is difficult to slow down the transmission speed. Although most internet cafe servers will limit the speed of each computer, it is much faster than ordinary broadband at home, but if your home is also equipped with optical fiber, you can forget it for a winter.

　　Diskless system in Internet cafes is a diskless network system adopted in Internet cafes. The Internet cafe machine is divided into two parts: the server and the client. Under the diskless system, the client does not need to configure the 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, and the files in the server hard disk can be read by all clients. This way is called the Internet cafe diskless system.

　　What are the advantages of diskless system? First of all, of course, it saves money, and there is no need to install a hard disk in every computer. Secondly, the hard disk of Internet cafe server is mostly used.High-speed enterprise hard diskForm arrays, and some even use them directly.Enterprise SSDThis will give consumers an unusual user experience, but the cost will be less than that of installing SSD or high-speed mechanical hard disk on every computer. Moreover, with the diskless system, every time a customer starts to read, it is a brand-new mirror system (or uses a restore card).It is equivalent to reloading the system every time it is turned on, which avoids the impact of computer jamming caused by cache garbage generated by ordinary consumers’ daily use at home, so that the computer experience of Internet cafes is better.

　　Every time the Internet cafe reads the system, it is very streamlined, except for most software that has nothing to do with the game, such as guards, so there will be very few background programs when you run the game, and the computer will naturally run a little faster.

　　Everything happens for a reason. After reading the above content, I believe everyone probably understands why most Internet cafes are so fast. In addition to not being able to make a diskless system, netizens can actually use some tips such as installing solid-state devices to make their hosts smooth. Although this is the case in theory, we can’t get enough information from the paper. Next, we PConline will go deep into Internet cafes to conduct on-the-spot hardware research and testing, uncover the secrets of computer hardware in Internet cafes, see what the specific hardware models favored by Internet cafes are different from those of ordinary consumers, and what the main installation logic of Internet cafes is now. Pay attention to PConline and Lin Dong. See you next time.
