Are you running on a 100 Mbps Ethernet connection?  If so, are your NIC
and switch port _both_ in full-duplex mode?  Fluke and other companies
make hardware lan testers that can test a connection for a number of
problems.  You could also try running a trace with Ethereal - it can show
you the delta times between packets and graph TCP throughput.  Which
version of Windows are you running?  Try running "netstat -es" - on my
Win2K box it shows Ethernet, IP, UDP, and TCP statistics including
discards and retransmits.
