Vibora

结论
1、在MAC环境下，用siege测试，相同的并发和请求数，Sanic和Uwsgi的表现遥遥领先，测试几十遍，sanic的QPS惊人的可以彪到7K以上，还要优化空间，Uwsgi参数优化后最大也可以到4K以上，其他框架表现平平，其中网络极力推荐的Tornado和Gunicorn(gevent)也没有Sanic出色。
2、在Mac和其他Linux环境中，用wrk测试，Vibora的表现艳压群芳，无与伦比。

综合下来，Vibora, Falcon, Gunicorn 整体表现不错，进入三强。
尴尬的是：尽管Sanic在各平台表现也很好，但是整体下来没有进入三强，很可惜。。。想哭😢
第一天测试sanic秒杀全场，第二天vibora秒杀sanic，我只好换各种姿势，最后证明还是vibora牛B一点。。。

备注
使用mac压力测试推荐siege或者wrk，ab有时候会出现超时或退出，不是很稳定。
Debian整体性能稍占优势，Ubuntu是基于Debian，建议以后微服务os选用debian。
