以下分别测试我本地的虚拟机和 VPS 上 Nginx + php-fpm 的性能
我的本机虚拟机测试，配置为PD930 双核3.0G，2G内存，给虚拟机分配的是 1G 内存，安装的系统为 CentOS 5.4 64bit
测试内容为
<?php phpinfo();?>
500 并发测试，CPU使用率到了30%，系统负载在10左右，页面打开还是飞快
[root@localhost ~]# webbench -c 500 -t 30 http://127.0.0.1/

2000 并发测试，CPU使用率35%，系统负载在18左右，页面打开还是飞快

5000 并发测试，CPU使用率30%，系统负载到了35，页面打还速度还不错，看了这数据，前些天说的那个1500万PHP请求也没啥了

还不过瘾，变态一下，10000并发
10000 并发，CPU使用还是不到30%，系统负载从60左右一直升到1000左右，晕死！居然还能打开！只是有点卡！负载到600多的时候居然不卡！疯了，我这还是虚拟机，webbench 还是在自己机上开的，汗，太强了
