tcp response-time to long

[klausc127]

Hi,
my problem: from a microcontroller-board tcp client i have to get data from a server. the server is on Windows 7 written in C#. It works fine, but the response-time from the server is about 0,5 sec. I would need abaout 0,1 sec. The connection seems to be ok, acknowledge and echo are within 0,001 sec , only the data-repsonse needs more. i asume it has to do with waiting for more date-packets from the client but don't know.
How can I adjsut something to get it faster?
(or other program-language or other protocol like udp...? )
Thanks for any advice.
Klaus

Addendum:
this also occurs when the windows system is directly connected to the micro without router or switch. In any of the configurations it appears the same 0,5sec.

Sounds like a badly written server program!
