# koa-benchmark

比较koa和koa2和express性能

![Preview](https://raw.githubusercontent.com/17koa/koa-benchmark/gh-pages/assets/preview.png)

## 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
```

## Results

```

v4.0.0
➜  koa-benchmark git:(master) ✗ npm -v

## 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
