如何在python中提高发送请求的速度？

import aiohttp
import asyncio

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    urls = ['http://example.com' for _ in range(100)]
    async with aiohttp.ClientSession() as session:
        tasks = [fetch(session, url) for url in urls]
        responses = await asyncio.gather(*tasks)
        print(responses)

# Python 3.7+
asyncio.run(main())

import requests

session = requests.Session()
for _ in range(100):
    response = session.get('http://example.com')
    print(response.text)

import concurrent.futures
import requests

def fetch(url):
    response = requests.get(url)
    return response.text

urls = ['http://example.com' for _ in range(100)]

with concurrent.futures.ThreadPoolExecutor(max_workers=10) as executor:
    futures = {executor.submit(fetch, url): url for url in urls}
    for future in concurrent.futures.as_completed(futures):
        url = futures[future]
        try:
            data = future.result()
        except Exception as exc:
            print(f'{url} generated an exception: {exc}')
        else:
            print(f'{url} page length: {len(data)}')
