based on libuv libuv
libuv是一种高性能的、跨平台异步的 I/O 类库，nodejs也使用到了它。
由于nodejs是如此的广泛和流行,可以知道libuv是快速且稳定的。
利用uvloop可以写出在单CPU内核下每秒钟能够发出上万个请求的Python网络代码

TCP, HTTP 请求的性能比较
uvloop-blazing-fast-python-networking
uvloop makes asyncio fast. In fact, it is at least 2x faster than nodejs, gevent, as well as any other Python asynchronous framework.
The performance of uvloop-based asyncio is close to that of Go programs.
Uvloop最终目的使得Asyncio更加快速
使用
pip install --upgrade pip
pip install uvloop
# 1
# To make asyncio use the event loop provided by uvloop, you install the uvloop event loop policy:
import asyncio
import uvloop
asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
# 2
# Alternatively, you can create an instance of the loop manually, using:
import asyncio
import uvloop
loop = uvloop.new_event_loop()
asyncio.set_event_loop(loop)
