aiohttp 与 requests 网络请求比较

下面是aiohttp异步请求，与常用的requests请求比较，差距还是蛮大的，其中ensure_future这种方式与for循环调用也存在一些差距

import asyncio
import aiohttp
import time


async def task_req():
    # 耗时0.1483309268951416s
    async with aiohttp.ClientSession() as session:
        async with session.get('http://baidu.com') as resp:
            print(resp.status)


async def for_req():
    # 耗时2.0457730293273926
    async with aiohttp.ClientSession() as session:
        for i in range(100):
            async with session.get('https://baidu.com') as resp:
                print(resp.status)


def sync_req():
    # 耗时 11.768546104431152
    for i in range(100):
        requests.get('https://baidu.com')


if __name__ == '__main__':
    s = time.time()
    # 第一组
    # sync_req()    
    # 第二组
    loop = asyncio.get_event_loop()
    # tasks = [asyncio.ensure_future(task_req()) for i in range(100)]
    # loop.run_until_complete(asyncio.wait(tasks))
    # 第三组
    loop.run_until_complete(for_req())

    print(time.time() - s)
