I am trying to use Mathematica as tcp server for computer vison, but I run into problem with speed. Mathematica recieves images from python and it takes very long time to accept the image, if I use C# to Python (full HD) everything works just fine. This is the code from Mathematica:

Port = 5005; Ip = "127.0.0.1"; message = 0; listener = "0"; outSocket = 0;  startSession[] := (   listener =      SocketListen[{Ip, Port}, recieveMessage,       HandlerFunctionsKeys -> {"DataByteArray"}];   )  getMessageLength[msg_] := (   ImportByteArray[Part[msg, 1 ;; 4], "Integer32"][[1]]   )  t = 0; messageBuffer = {}; msgLenght = 0;  recieveMessage[x_] := Module[{sameLength},   If[Length[messageBuffer] == 0, messageBuffer = x["DataByteArray"];    msgLenght = getMessageLength[x["DataByteArray"]];    t = AbsoluteTime[];     Echo[msgLenght];    ,    messageBuffer = Join[messageBuffer, x["DataByteArray"]];    ];    sameLength = msgLenght == Length[messageBuffer];    If[sameLength,    messageBuffer = {};    Echo[AbsoluteTime[] - t];    ,    Return[0];    ];   ] startSession[] 

and here Python:

import socket import time import struct  TCP_IP = '127.0.0.1' TCP_PORT = 5005  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((TCP_IP, TCP_PORT))  message = "x" * (1920*1080*3)  mess = struct.pack('i', (1920*1080*3 + 4) ) mess = mess + message s.send(mess) s.close() 

The main problem is not join, even if I do not store recieved data it does not change the time much and is still around 9 seconds.

Do you have any idea how to speed it up? I need to get to times below 0.1 seconds per image. Python and Mathematica run on the same computer.

Thank you for any ideas.
