人家都说了，它叫simple嘛。。。

Nginx，永远不要将语言自带 Server 放到你的生产环境。

我在Win8上测试的，nginx 1.5.8，Python 2.7.6
同一个网站，nginx跑在80上，Python SimpleHTTPServer跑在7777上。
没有任何访问的时候nginx占用2.1MB，Python占用7.6MB，如下图：

我使用ab同时对两个服务进行测试，两者的内存占用方面都没有变化，估计是我的测试页面不够大的缘故，但是CPU占用方面nginx高于SimpleHTTPServer，如下图：

但同时nginx的效果比SimpleHTTPServer高很多，下面是ab的报告：

nginx的效率是SimpleHTTPServer的4倍左右，另外需要提的是SimpleHTTP在并发的时候经常出现卡死的情况，它毕竟只是一个测试用的服务，使用需谨慎。这win下的结果，linux下，ng的性能才能真正发挥。。。
