1) 100 Half will in many cases provide worse performance than 10 Half.  Speed
and duplex are definately the first thing you want to correct, if possible.  The
most common way to correct this is to set the duplex negotiation to auto on both
the switch and client.

2) Have we tried to benchmark throughput using another application, like HTTP?
Bittorent, NFS? 

3) Ethereal is your friend.  take a capture and run it through Shane Ostermann's
tcptrace application.  It will breakdown the TCP level dynamics, showing packet
loss and retransmissions, etc.

HTH.

Regards,
Max
