Richard, thanks a lot for your hint, that was completely new for me. Nagle's optimisation is definitely a good idea in most cases.
By the way, do you have an idea how to access the underlying socket to modify the behavier via the setsockopt function to disable Nagle's algorythm in my special case (i need speed for small packets) ? Thanks a lot Hans -- http://mail.python.org/mailman/listinfo/python-list
