php性能优化(一)压力测试工具篇

ab使用

<code>  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。。</code>

要执行 1000 次的 connection, 20 次的 concurrent (并行, 同时):
语法: ab -n 1000 -c 20 www.baidu.com

产生出来的结果. 要注意的是以下几个:

§ Time taken for tests: 总共执行花了多久的时间.(以上 1000 次共多久)

§ Requests per second: 每秒平均可以处理多少个 connection.

webbench

最多可以模拟3万个并发连接去测试网站的负载能力,个人感觉要比Apache自带的ab压力测试工具好,安装使用也特别方便。
