結論
一、在MAC環境下，用siege測試，相同的併發和請求數，Sanic和Uwsgi的表現遙遙領先，測試幾十遍，sanic的QPS驚人的能夠彪到7K以上，還要優化空間，Uwsgi參數優化後最大也能夠到4K以上，其餘框架表現平平，其中網絡極力推薦的Tornado和Gunicorn(gevent)也沒有Sanic出色。
二、在Mac和其餘Linux環境中，用wrk測試，Vibora的表現豔壓羣芳，無與倫比。

綜合下來，Vibora, Falcon, Gunicorn 總體表現不錯，進入三強。 尷尬的是：儘管Sanic在各平臺表現也很好，可是總體下來沒有進入三強，很惋惜。。。想哭😢 第一天測試sanic秒殺全場，次日vibora秒殺sanic，我只好換各類姿式，最後證實仍是vibora牛B一點。。。 Index Frameworks Requests/Sec Version 1 Vibora 15316.90 2.0.17.1 2 Falcon 4697.89 0.8.3 3 Gunicorn 3666.68 0.0.6 備註 使用mac壓力測試推薦siege或者wrk，ab有時候會出現超時或退出，不是很穩定。 Debian總體性能稍佔優點，Ubuntu是基於Debian，建議之後微服務os選用debian。
