Throw out the Realtek cards and buy a good nic. I had a server (clone
P3) with network performance issues, saving files to the server would
take forever but reading from the server would work okay. I finally
replaced the Linksys card (recognized as a dc, I think) with an em, all
fixed.
It cold also be a duplex issue, look for collisions on the network
interfaces. Some cards will ignore you when you tell them what duplex
to use.
