In the Taobao environment, assuming that we stress test the TPS is 100, then the system's daily throughput =100*11*3600=396 million This is in the case of simple (single URL), some pages, a page has multiple request, the actual throughput of the system is also small Regardless of time-to-think (T_think), there is a relationship between the measured TPS value an

The baseline has finally been developed, the performance of the server and the ability to withstand the pressure on the Internet, not find the right test tools can be used. So I wrote a test tool based on MFC.The startup interface is as follows:After setting the parameters, run as follows:Run through the following interface:The source path is as follows: Https://github.com/RibbonServyou/TCPTestToolNote: 1,

people know that the server's IP, if designed to connect only two ports can send data, then there will always be people trying to do not give him the authorization of the port, if this will seriously affect the person's communication, It may even affect the server's normal operation.2 Why do I need a user name to find a user? Because everyone will get two two username, these two usernames are unique and randomly assigned, only the parties know, so you can find their own user name to another use

This is a creation in Article, where the information may have evolved or changed. The C + + (16Gbps) is 4 times times the performance of Go (4Gbps) in the case of a test before, without any optimizations, refer to http://blog.csdn.net/win_lin/article/details/40744175 This time, for the TCP part, go was optimized, and the test results were satisfying. Go single pr

When Transaction Controller is used, the average response time can also be displayed in Transaction Median: Median, the response time of 50% users 90% Line:90% User response time min: Minimum response time Max: Maximum response time error%: number of requests/requests with errors in this

the establishment of TCP connections during the three handshake session in the process of a middle state, very short, basically with netstat you are very difficult to see this state, Unless you deliberately write a client test program, intentionally three times TCP handshake process of the last ACK message is not sent. Therefore, when the client's ACK message is

Use ping and net view commands to test TCP/IP connection 1. To use the Ping command to test the connectivity of TCP/IP, use the ipconfig command to make sure that the network adapter is not in the "Media disconnected" status. For more information, see "NOTE ". 2. Open a command prompt and use the IP address to ping the
