The following are ten free Web load/stress testing tools, you can know how much concurrency your server and your WEB application can withstand, and the performance of your website. I believe that the development team of the ticket booking website of the Beijing Organizing Committee does not know such a test tool.

An example code about improving php program performance and load testing. if you need it, you can see how to improve the performance of your program. calculate the execution time. the following simple method can be used to calculate the execution time of a program (subtle). The code is as follows: $ start_ti... an example code about improving
programs.
Output in the command line:
./AB-n number_of_total_requests \-C number_of_simultaneous_requests \Http: // your_web_server/your_php_app.php
For example:
./AB-n 1000-c 50 http://www.domain.com/myapp.php
At the same time, AB will send 50 concurrent requests to http://www.domain.com/myapp.php, with a total of requests.
The test results may be as follows:
