WordPressが重いような気がしたので、eAcceleratorを導入してみる。
インストールは、pbone.netより適当にRPMを拾ってくるだけでおｋ。
CentOS5互換のRHEL5用を使用する。

[root@jacksonville ~]# wget ftp://ftp.pbone.net/mirror/ftp.freshrpms.net/pub/freshrpms/pub/dag/redhat/el5/en/i386/dag/RPMS/php-eaccelerator-5.1.6_0.9.5.2-4.el5.rf.i386.rpm
[root@jacksonville ~]# rpm -ivh php-eaccelerator-5.1.6_0.9.5.2-4.el5.rf.i386.rpm
[root@jacksonville ~]# /etc/init.d/httpd restart

Apache Benchを試してみて、入れる前と比べてみる。
