Yeah, that's what I couldn't think of the other day.  The principal
report was here:
http://archives.postgresql.org/pgsql-general/2005-01/msg01231.php

    By default, Windows XP installs the QoS Packet Scheduler service.
    It is not installed by default on Windows 2000.  After I installed
    QoS Packet Scheduler on the Windows 2000 machine, the latency
    problem vanished.

Now he was talking about a local connection not remote, but it's still
something worth trying.
