Generally in a network environment you want to 'strap' ports to speed/duplex settings and avoid autonegotiate as this can cause problems... when both ends are set to 'auto' it almost always causes problems such as links re-negotiating out of the blue.. this kinda sounds like what you are experiencing.
I don't know what the commands are but if possible I would 'strap' both nics to 100/full. I have also found that some nic's (drivers) don't really support 100/full all that well (in general not just under linux) and they actually perform better when set to 100/half.

Network performance seems a little faster than before but still a little slow compared with what I thought would have been possible with a 100TX crossover network. Must be a limitation of the cheap cards. Thanks for your help.
