服务器基准测试php性能

我在不同的公司有几个托管帐户，我正在尝试评估哪一个会以最快的速度安装Wordpress（而不必先在每个公司上安装Wordpress）

我找到了一个php基准测试脚本，试图确定哪一个工作得最好，结果很奇怪

您必须安装wordpress才能分析每个版本的性能。事实上，您应该在这三个版本中安装完整的wordpress环境，我的意思是，所有wordpress插件都应该安装，因为它们可能会对性能产生很大影响。此外，apache、mysql和php应该在所有三台服务器中进行相同的调优

一旦这样做，就可以使用jMeter(http://jmeter.apache.org/)要真正测试您的服务器，并查看您的服务器可以提供多少请求。
