By chance, the project encountered a huge performance problem, mainly in terms of network, from China. Ping One in the United States Server Yes 256 Ms And from the United States Ping One in the United States Server Only 5 ms The severity of this problem directly causes users in China to be unable to accept installation in the United States. Server Application onProgramResponse speed.
Traditional CS Architecture or BS Architecture: a large amount of data is transmitted from the server to the client: Generally, the client sends a request to the server, then the server responds, and finally returns the result to the client, this should be the most typical application. If the network between the client and the server is not ideal, a large amount of data transmission will inevitably lead to unacceptable system performance. From the perspective of the project we tested, 10 Minutes 4 Business, the traffic generated in 10 m Above. Is there any solution to avoid this transfer? The answer is yes, Citrix Is the solution to this problem.
CitrixHow does it work?
Is technology going backwards? Terminal Era (end users) and diskless workstation era? It works a bit like it, but it's not all done. Citrix Like a software platform, if you have used VMWare Or Virtualpc You can see that the operating system is just a software. Citrix There are also clients and servers, and all the software is installed on the server. Its advantages are obvious, such as unified deployment, version control, and software saving. License More secure. Citrix The biggest advantage is to reduce the network traffic between the server and the client, because during the operation, only the mouse, keyboard operation, and screen update are transmitted between machines, if no business data is transmitted between the client and the server Citrix According to official documents Microsoft Cooperation provides a secure layer between networks, even if only data is used 128 BIT data encryption.
There is a customer case that Latency Yes 220 ms The Citrix Performance is improved after the architecture 48 Times.
Some disadvantages are inherent:
LIf there is no network, the system cannot work at all.
LAlthough the traffic between networks is reduced, any application is dependent on the network, and the speed of the network is a problem,CitrixThis problem was solved to a certain extent.
LClientLicenseFees, which are said to be very high, cannot be found in China.

I hope that interested friends can study the software and download it from the plug-in.
