Python Flask vs Ruby Sinatra vs Go Martini vs Node Express

Flask, Sinatra, Martini, Express

题外话一：
最近一段时间，Cloud Insight接连发布了三种语言（Python, Node, Ruby）的SDK，Cloud Insight Agent也迎来了重大突破，发布了Windows监控第一个版本，总算可以松口气写点东西了~

题外话二：
偶然的机会看到一篇blog，文中详细的介绍了Flask(Python), Sinatra(Ruby)以及 Matini(Golang)这三类微型框架的用法，并提供了各个框架在Docker下的部署方式。然而，美中不足的是没有提供各个框架的性能对比情况，经过一番搜罗，发现了一篇对现今主流框架做性能对比的文章，找到两者的结合点，于是才有了今天这篇文章~

回归正题，之所以选择Flask(Python), Sinatra(Ruby), Matini(Golang)和Express(Node)，主要是经验所限以及个人比较喜欢这类微型框架，下面我们就对各个框架在同等条件下的性能表现一探究竟。

总结：

可见，Matini(Golang)和Express(Node)性能优势比较明显，也在意料之中，Flask(Python)表现中规中矩，相较之下，Sinatra(Ruby)的性能简直是没法忍（PS: 我不是Ruby黑）！感兴趣的亲们可以在自己的环境测试下。完。
