Apache自带的性能测试工具ab的使用

刚开始的时候,对于压力测试感觉就是空白一片,后来查了查资料感觉其实一旦入门,一切不会是想象中那么难。

????进入cmd命令行模式,把目录切换到apache下的ab.exe所在的路径,我装的是集成的appserv,所以路径是:D:\AppServ\Apache2.2\bin,这个都是次要的,只要有Apache的ab.exe就能够进行压力测试。

???然后在这个下面键入:ab -n 1000 -c 50?http://localhost/site/index.php

???然后就会返回结果了:

D:\AppServ\Apache2.2\bin>ab -n 1000 -c 50?http://localhost/site/test.php
