动态web页面 的速度跟nginx服务下的静态页面的支持速度，天壤之别啊。 (dynamic pages is so slow comparing to static pages served by nginx)

今天心血来潮，比较了一下静态服务器和动态WEB服务器，在同样并发下的相应速度。 前者是后者速度的50倍。 在我的机器上轻松支撑到 15K req/s, 而 使用了cache的 rails : 300 req/s. 哎。。。 (in short: nginx serving static page is 50 faster then rails server using cache)
