Use of the Apache built-in Performance Testing Tool AB

The Apache server kit comes with AB. You only need to install Apache without installing AB. The AB file is located in the directory % apachehome %/bin (%%apachehome.pdf for aapcheche ), you can copy the AB .exe file and use it independently.
Suppose we want to test a PHP forum system. One of the performance test cases is: "processing 50 concurrent requests at the same time and running 1000 indexes. PHP Homepage ", we can enter AB-N 1000-C 50 http: // 172.16.11.180: 88/BBS/index in cmd shell. PHP. After running, AB automatically displays the test results.
