Well, if this precise use case is really important for you, I suggest
using Wireshark (or any other packet analyzer) to see what happens in
terms of latency between packets over the wire.
Something else: try replacing "localhost" with "127.0.0.1", perhaps your
DNS resolution eats a lot of time.

I don't know, but I suspect the difference is more in the TCP stack
implementation than in the sockets layer.
In any case, I'm gonna close this bug, as this is very likely not a
Python problem. Please ask further questions on comp.lang.python, lots
of people there may help you :)
