You say the 10BaseT was only a few K/sec. You should see 800K/sec or so
for a 10BaseT connection (assuming of course you are going over a local
connection to another fast machine). Even on a lowly P90 running Linux I
regularly see 1600 K/sec with 100BaseT. So I don't think its a limitation
of Linux.
With the 10BaseT operating this slowly its likely a bad cable, network
card or something.... which would also impact the performance of
the 100BaseT. If plugged into a managed hub or switch, check
the statistics for bad packets, collisions, etc. You might try
another cable, network card, port on hub, etc.
