如何在python套接字中更快地发送大消息？

def chunk(message, chunk_size):
    return [message[i:i+chunk_size] for i in range(0, len(message), chunk_size)]

import threading

def send_chunk(sock, chunk):
    sock.send(chunk)

def send_message(sock, message, chunk_size):
    chunks = chunk(message, chunk_size)
    threads = []
    for chunk in chunks:
        thread = threading.Thread(target=send_chunk, args=(sock, chunk))
        thread.start()
        threads.append(thread)
    for thread in threads:
        thread.join()

import socket

def set_socket_buffer_size(sock, buffer_size):
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_SNDBUF, buffer_size)

sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
