使用Apache的ab工具进行网站性能测试_HTTP压力测试工具

压力测试、相信大家都有做过吧、或者是即将开始做、那么用什么工具来进行压力测试呢

Apache附带的压力测试工具ab、非常容易使用、并且完全可以摸你各种条件对Web服务器发起测试请求

ab可以直接在Web服务器本地发起测试请求、这对于需要了解服务器的处理性能至关重要

因为它不包括数据的网络传输时间以及用户PC本地的计算时间

下面我们开始压力测试（环境说明：win7、需要在命令行cmd中切换至ab.exe所在目录）

执行以下命令：

ab -n1000 -c10 http://localhost/index.php/

执行结果如下：
