如果你在Linux下用Apache Bench (ab)测试我这个网站的话，就会发现服务器不是常见的Apache, 而是 nginx.
nginx是一个小巧而高效的Linux下的web服务器软件。开发人员 Igor Sysoev 来自俄罗斯，nginx的话其实已经在一些俄罗斯的大型网站上运行多年，相当的稳定，最近才在美国开始知名起来。
而另外一个热门的web服务器软件是Lighttpd，因为运行在Youtube的后台，所以知名度很高。Lighttpd特色在于它能做Flash streaming和对fastcgi的支持，这样对于Ruby on Rails之类的程序提速不少，比起Apache要好很多。
但是 nginx 要比 Lighttpd 更稳定，功能上并不弱于Lighttpd，差不多什么都有，而且比Lighttpd对于URL rewrite的支持更完善一点。
不管是 nginx 还是 lighttpd, 对于用来提供静态文件都要比Apache好很多很多，主要就是占用的内存小，Apache和这两个小巧的服务器软件来比实在是个庞然大物啊。

另外lighttpd和nginx 在fastcgi的支持中，没有明显的差异，就没有将结果记录起来。
从上面的结果来看，在静态支持中，lighttpd和nginx 是比apache优胜很多很多的。
即使Apache2+worker，在支持PHP方面，还是不太让人满意。
另外从运行时对内存、CPU开销来看，最大是Apache，Lighttpd 和 Nginx 比较接近，但是Lighttpd相比Nginx更占资源一些。
因此，如果不考虑虚拟主机安全设置的问题，Nginx无疑是最好的选择，其次是Lighttpd。

测试工具没错，但是测试方法没说明每个web server的配置，这样你用测试工具webbench -c 500 -2这几个参数加压的时候会给web server造成不公平的测试环境，实际点说，我用得一台dell1950的机器跑apache2.2.4 worker高峰期10个小时的访问量是平均3000req/s,负载不超过0.8，

这位仁兄说得很好... 参数配置一般是基于应用上而灵活配置的.但简单的页面测试,反而不加参数还倒能证明点什么出来.呵呵... 你的机器配置得不错...
