題外話一：
最近一段時間，Cloud Insight接連發布了三種語言（Python, Node, Ruby）的SDK，Cloud Insight Agent也迎來了重大突破，釋出了Windows監控第一個版本，總算可以鬆口氣寫點東西了~
題外話二：
偶然的機會看到一篇blog，文中詳細的介紹了Flask(Python), Sinatra(Ruby)以及 Matini(Golang)這三類微型框架的用法，並提供了各個框架在Docker下的部署方式。然而，美中不足的是沒有提供各個框架的效能對比情況，經過一番蒐羅，發現了一篇對現今主流框架做效能對比的文章，找到兩者的結合點，於是才有了今天這篇文章~
迴歸正題，之所以選擇Flask(Python), Sinatra(Ruby), Matini(Golang)和Express(Node)，主要是經驗所限以及個人比較喜歡這類微型框架，下面我們就對各個框架在同等條件下的效能表現一探究竟。

總結：
| Web framework | avg | min | max |
|---|---|---|---|
| Flask(Python) | 168ms | 26ms | 295ms |
| Sinatra(Ruby) | 496ms | 180ms | 10507ms |
| Martini(Go) | 48ms | 14ms | 112ms |
| Express(Node) | 60ms | 26ms | 171ms |
可見，Matini(Golang)和Express(Node)效能優勢比較明顯，也在意料之中，Flask(Python)表現中規中矩，相較之下，Sinatra(Ruby)的效能簡直是沒法忍（PS: 我不是Ruby黑）！感興趣的親們可以在自己的環境測試下。完。
