Apache设置相当标准,但Nginx设置被大量定制;它们在基准测试结果下面列出。
我使用名为Siege v3.0.2(http://www.joedog.org/siege-home/)的基准测试工具为单个并发用户(c1),10个并发用户(c10)和100个并发用户(c100)生成结果;结果如下: Apache结果:

我关心的数据来自于c100“PHP”和“Combined”结果。Apache相当快,我想知道为什么会这样,考虑到所有在线基准测试都表明相反的情况。
两个服务器都是:
1. 采用四核Xeon处理器 2. 8GB内存 3. 连接到同一网络上的MongoDB v2.2数据库 4. PHP-FPM设置为使用100个PHP进程
Apache(设置非常接近原始状态):
1. 运行在CentOS 5上 2. Apache 2.2 3. mod_php Nginx:
1. Ubuntu 13.04 2. Nginx 1.2.6 3. PHP-FPM(FastCGI)具有100个PHP进程

非常感谢您的帮助,我需要一些关于如何使Nginx更快的建议。如果可能的话,我想避免对内核和TCP/IP进行调整。
