求的响应情况. Each request in the scene has a response time, where 50% of the user's response time is less than 275 milliseconds, 66% of the user response time is less than 298 milliseconds, and the maximum response time is less than 11843 milliseconds. In the case of concurrent requests, the CPU is not actually processed at the same time, but is rotated on a per-request basis, so basically the first time of the request is approximately equal to the second

The full name of AB is apachemeter, which is an Apache network stress testing tool. compared with LR and JMeter, AB is the simplest and most common Http stress testing tool I know. The AB Command has very low requirements on the computer that sends out the load and does not occupy high CPU and memory. However, it can also generate huge loads on the target server

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,

JMeter Stress Test (i) sets the number of threads in the thread group, that is, the number of concurrent users at execution time, and applies to concurrent tests for a single thread group. If the test requirements appear in the following scenario, how can you use JMeter to implement stress testing? That is how JMeter

In fact, the MySQL test is not so complex, in addition to some commonly used select\insert\update\deletc these, in fact, testing his concurrency is the most important. For example, in connection with the number of 1K, the concurrent volume can meet the current request \ Server performance, memory CPU usage. To be blunt, testing MySQL is testing his profile and concurrency and server performance. One, tools
