koa、koa2、koa2-async和express的压测性能比较

koa-benchmark

比较koa和koa2和express性能

Prerequisites

for OSX

brew install wrk

Test

首次测试，需要安装依赖，会比较慢

make all

不安装依赖，重复测试

make test

查看中间件请求测试

make test -f Makefile2

压力测试模型

假设支持100w
每个用户每天访问a次 (web.tools.com)
每天次数：100w * a
按照80/20原则，80%的访问集中在20%的时间内
100w * a * 80%  / 4.8小时
假设对用户来说每次访问6秒钟是可以接受的
(100w*a*80%/4.8h)*6=测试用并发数据
