非常抱歉， 在整理My Art时看到此篇，但没有记录来源.

我只翻译我觉得可参考的信息， 也请看官自取.

文中涉及到基准测试软件

Siege (version 2.6.1), Wordpress blog CMS (version 1.5.2), WP-Cache plugin for WP (version 2.0), eAccelerator PHP-accelerator module (version 0.9.3) , mod_rewrite Apache module (Apache 1.3.33).

Wordpress在性能上的表现并不是被赞誉的, 我使用WP-Cache来缓存Web页面(ps: 和我一样  )

服务器装配:

• Dell PowerEdge SC1425 server
• 1 x 2.8GHz Intel XEON processor
• 2 x 80Gb SCSI (RAID 0)
• 512Mb RAM
• Debian GNU/Linux 3.1
• Apache 1.3.33
• PHP 5.0.5 (as module)
• MySQL 4.1.11 (with query cache enabled)

基准测试报告

• 单机
• 无网络损耗
• 使用参数: siege -u http://example.com/ -t30S -c20
• 清除所有缓存后做测试
• All hits to frontpage (not a realistic scenario)
• Static HTML == front page as pure HTML

查看下结果报告 :
