PHP uses ab in Apache to test the stress performance of the website_PHP tutorial

Open the installation path of the Apache server (I use WampServer). There is an executable program ab.exe in the bin directory, which is the stress testing tool to be introduced.

In the command line of Windows system, enter the directory where the ab.exe program is located and execute the ab.exe program. Note that double-clicking directly will not work correctly. 喎?http://www.Bkjia.com/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+ICAgICAgICBkOii72LO1L734yOtExcwpPGJyPgo8L3A+CjxwPiA8aW1nIHNyYz0="http://www.2cto.com/uploadfile/Collfiles/20140614/20140614091704240.jpg" alt="">
