Python requests vs aiohttp speed comparison

Environment: Centos7 python3.6

Test URL: www.bai.com

Test method: Crawl Baidu 100 times

Results:

aio:10.702147483825684s
Requests:12.404678583145142s

The speed of the asynchronous framework is still significantly improved.

The following contribution code:

Import aiohttpimport timeimport requestsimport asynciodef test_requests (): "" "    test requessts request Baidu 100 times    " " Start = Time.time ()    url = "https://www.baidu.com" for    I in range:        requests.get (URL)    end = Time.time ()    print ("Requests:")    print (End-start)        async def aio_download (URL): "" "  aiohttp Download" "    async with Aiohttp." Clientsession () as session:        await session.get (URL) async def test_aio (): "" "    test AIOHTPP request Baidu 100 times    " " url = "https://www.baidu.com"    start = Time.time () for    I in range:        await aio_download (URL)    end = Time.time ()    print ("AIO:")    print (end-start) if __name__ = = "__main__"    : loop = Asyncio.get_event_loop ( )    Loop.run_until_complete (Test_aio ())    test_requests ()

Tips:

Requests do not use the session to repeatedly crawl a site test, because from the 2nd time, reading is the cache, no matter the crawl 50 or 100 times or more, the total time is within 1s.
