# portscan
> Python多线程和异步协程全端口扫描速度比较
### 设置ulimit为65535
> 因为是用socket连接，所以需要设置系统文件打开最大数
### 结果比较
> shodan随机选择一个IP：115.231.108.219，开放端口有
- 80
- 443
- 902
- 8000
- 9080
##### 线程池版
> 多线程方式采用线程池，节约创建新线程开销，超时5s，5000个线程
```
115.231.108.219 80
115.231.108.219 427
115.231.108.219 443
115.231.108.219 902
115.231.108.219 8000
115.231.108.219 9080
115.231.108.219 8300
已经超过4分钟了，不继续了。结束运行
```
##### asyncio异步版
> 超时5s，5000个协程
```
115.231.108.219 902
115.231.108.219 427
115.231.108.219 443
115.231.108.219 80
115.231.108.219 8000
115.231.108.219 8300
115.231.108.219 9080

> 在对于IO阻塞方面，异步操作要优于多线程 操作，且更节约系统资源。
