Its probably generating some stupid retransmits like the current
hacked around code does on PPP links. The other thing that may do it
is windows filling because of ack problems.

Thats nice to know.

Does changing the large windows option affect it. Can a third box log the
link and see what kind of mess you see in duplicates. How does 1.3.59 compare.
We need to pin this down - its I think got to be extra frames or window/ack
problems. The base performance goes well over 40Mbit/second on 100baseT
