本文介绍如何使用ApacheBench工具进行HTTP服务器基准测试。通过设置并发数和总请求数等参数，可以评估服务器的性能指标，如每秒处理请求的数量、响应时间和传输速率等。

ab 的全称是 ApacheBench ，是 Apache 附带的一个小工具，专门用于 HTTP Server 的 benchmark testing ，可以同时模拟多个并发请求。一般开发人员在进行真正的压力测试之前可以使用这个工具来进行自测，从而更好地掌握性能。

首先进入安装Apache下的bin目录，比如在我本机就是C:\Program Files\Apache Software Foundation\Apache2.2\bin，较常用的参数是n和c,

-n1000，指定总请求数，-c10，指定并发数

运行命令 ab -n 10000 -c 100 http://renmai-dev.china.alibaba.com/view/attention/index/1.html 和结果如下：

运行结果代码(重要参数：request per seconde 服务器每秒请求处理数)

C:\Program Files\Apache Software Foundation\Apache2.2\bin>ab -n 10000 -c 100 http://renmai-dev.china.alibaba.com/view/attention/index/1.html

请注意并发数最大为1024，取值不可大于此。接下来，比较一下压力更大的情况。
