如何通过并发处理提高Python网站的访问速度？

import threading

def handle_request(request):
    # 处理请求的逻辑代码
    pass

def serve():
    while True:
        # 监听请求并创建新线程处理
        request = get_request()
        thread = threading.Thread(target=handle_request, args=(request,))
        thread.start()

# 主函数
if __name__ == "__main__":
    serve()

from multiprocessing import Process

def handle_request(request):
    # 处理请求的逻辑代码
    pass

def serve():
    while True:
        # 监听请求并创建新进程处理
        request = get_request()
        process = Process(target=handle_request, args=(request,))
        process.start()

# 主函数
if __name__ == "__main__":
    serve()

import asyncio

async def handle_request(request):
    # 处理请求的逻辑代码
    pass

async def serve():
    while True:
        # 监听请求并异步处理
        request = await get_request()
        await handle_request(request)

# 主函数
if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(serve())

from functools import lru_cache

@lru_cache(maxsize=100)
def calculate_result(input):
    # 复杂计算的逻辑代码
    pass

def handle_request(request):
    result = calculate_result(request)
    # 处理结果的逻辑代码
    pass
