xcache使用速度实践测试
总体环境都是在vw的虚拟机上。
在word上可以按表格来统计，一目了然。
1、单机安装：
单机环境：
os:centos 6.6 x64
php:php5.5.26
mysql: mysql-5.5.45
nginx:1.8.0
网站：wordpress
2、mysql分开了和存储nfs，总共三台服务器
环境：
os:centos 6.6 x64
php:5.3.27
mysql:5.5.32
网站：wordpress
3、在单机上测试用了xcache,
1）、xcache的配置文件php.ini用在xcache.mmap_path = /tmp/xcache上，大小是64M
测试结果如下：
50个连接：
[root@mysql_server ~]# webbench -c 50 -t 30 http://192.168.168.238/

2)、把xcache缓存文件放在tmpfs文件系统中，tmpfs文件系统是在内存上。
php.ini配置文件改变为：
xcache.mmap_path = “/tmp/cache_php/xcache”
大小还是64M
挂载：
mount -t tmpfs -o size=64m tmpfs /tmp/cache_php
[root@clc-server lib]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 16G 3.6G 11G 25% /
tmpfs 1.9G 0 1.9G 0% /dev/shm
/dev/sda4 13G 711M 12G 6% /application
/dev/sda1 190M 32M 149M 18% /boot
tmpfs 64M 14M 51M 21% /tmp/cache_php
测试结果：
并发100，时间30秒：

比较：用在内存上速度要比用在磁盘上快。
4、在单机上测试没有用xcache
