ab位于%ApacheHome%/bin目录下(“%ApacheHome%”为Aapche安装路径)，你也可以把ab.exe文件copy出来，独立使用。以上参数最常用的是-n 在测试会话中所执行的请求个数;和-c 一次同时产生的并发请求个数。
1 概述
ab(ApacheBench)是Apache自带的超文本传输协议(HTTP)性能测试工具。 其设计意图是描绘当前所安装的Apache的执行性能， 主要是显示你安装的Apache每秒可以处理多少个请求。
2 使用
2.1 安装
Apache服务器套件自带ab，只要安装Apache即可，无需另行安装ab。ab位于%ApacheHome%/bin目录下(“%ApacheHome%”为Aapche安装路径)，你也可以把ab.exe文件copy出来，独立使用。
