AFAIK, the receive window for TCP is automatic. The TCP protocol specifies that
the receive window should be calculated dynamically by a moving average of the
number of timeouts, of which the exact equation escapes me. Linux/*nix all do
this but I think the windows implementation is just broken ;)

Under linux you can specify the MTU for an interface using ifconfig and the mtu
key word.

eg. "ifconfig eth0 mtu N" where N is the MTU size.

I remember playing around with this when I first got cable a couple of years
ago, and it didn't make much difference. You might have more luck with Ultra.
