Nginx的PHP一直比Apache 2.2慢

注：我问这首先在StackOverflow并发送到这里。 我希望重复是可以的。

在使用Ubuntu 13.04上完全库存的软件包比较Apache 2.2和Nginx 1.2.6的负载testing中，我发现Nginx PHP请求的性能比Apache PHP的要低。 如果可能的话，我正在寻找指导，让我们的Nginx性能超过Apache的性能 。

Apache的设置相当标准，但是Nginx的设置是相当的定制的; 它们被列在基准结果之下 。

我使用名为Siege v3.0.2的基准testing工具（ http://www.joedog.org/siege-home/ ）为单个并发用户（c1），10个并发用户（c10）和100个并发用户（ C100）; 结果如下：

• Apach AuthLDAPNURL能指向树的根吗？
• 在fcgi看到请求之前使mod_rewrite规则进行处理
• 需要删除创build的头中不需要的前缀
• PHP文件被未知的实体caching
• 阻止来自开发服务器和静态资产域的僵尸/蜘蛛

我所关心的数据来自c100“PHP”和“Combined”结果。 阿帕奇是相当快一点，我想知道如何在网上所有的基准testing显示相反。

这两个服务器是：

1. 运行在四核至强处理器上
2. 8GB内存
3. 连接到同一networking上的MongoDB v2.2数据库
4. PHP-FPM被设置为使用100个PHP进程

Apache （设置非常接近股票）：

1. 在CentOS 5上运行
2. Apache 2.2
3. mod_php的

Nginx的：

1. Ubuntu 13.04
2. Nginx 1.2.6
3. 具有100个PHP进程的PHP-FPM（FastCGI）

任何有关使Nginx更快的build议将不胜感激。 如果可能，我想避免内核和TCP / IP调优。
