为什么服务器要花这么多时间来接收消息？Python套接字

我正在尝试编写一个简单的共享屏幕脚本。出于某种原因，服务器接收消息需要花费大量时间。我不知道问题出在哪里。 如果你有一个解决方案，或者有一个加速过程的方法，那将非常有帮助。无论如何，我很感激你的帮助

服务器：

import socket
import pickle
import select
import numpy
import cv2

def receive_msg(socket, HEADERSIZE):#receive message
    try:
        readySockets, _, _ = select.select([socket], [], [], 0.02)
        if readySockets:
            msgLen = socket.recv(HEADERSIZE)#receive the header/the message length
                
            msgLen = int(msgLen)#convert fron bytes to int
            msg = socket.recv(msgLen)#resive the size of the message
                
            while len(msg) < msgLen:#if dont receive the full message / if the size of the message smaller than the size that the message sepose to be 
                msg += socket.recv(msgLen - len(msg))#add to the message the part that missing (the full size of the message - the size of the message that the program received)
                        
            msg = pickle.loads(msg)#extract message
        else:
            msg = False
    except: 
        msg = False
        
    return msg#return the complite massage

HEADERSIZE = 10

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((socket.gethostname(), 1243))
s.listen(5)
    
clientsocket, address = s.accept()

while True:
    # now our endpoint knows about the OTHER endpoint.
    msg = receive_msg(clientsocket, HEADERSIZE)
    if msg is not False:
        image = cv2.cvtColor(msg, cv2.COLOR_RGB2BGR)#numpy array to open cv image
        cv2.imshow("image", image)#show image
        
        cv2.waitKey(1)

需要多长时间？你的屏幕有多大？从客户端到服务器有多少带宽？延迟为5.4秒。屏幕是高清的。每条消息都是6220964字节。这是延迟（发送/接收之间的时间）还是延迟（多次发送之间的时间）？是多次发送之间的时间。因此，您是否验证了延迟实际上来自传输图像，而不是捕获、转换、打包图像并将其推送到套接字？需要多长时间？你的屏幕有多大？从客户端到服务器有多少带宽？延迟为5.4秒。屏幕是高清的。每个消息都是6220964字节。这是延迟（发送/接收之间的时间）还是延迟（多次发送之间的时间）？是多次发送之间的时间？因此，您是否验证了延迟实际上是来自传输图像，而不是捕获、转换、打包图像并将其推送到套接字？
