Can you elaborate a bit more on the comment below?
As a later poster said, problem in the switch. For an interesting time, check out:

This is talking about half-duplex 10BaseT issues.
I recently saw a switch where I turned off full duplex on client and server, forcing everything including switch ports to half-duplex and watch the thruput numbers (sequential read and write) go up 40-60%. And that was Sun->Sun numbers. Thruputs to the filer went up also.
I have ceased *expecting* anything from switches. I measure them now and compare them in full and half duplex. So far, at least, all switches work well in at least one mode.
And damn, those four $199 hubs are pretty good:-)

One thing to try is half-duplex. I know it sounds weird, but in some cases it seems to perform better than full-duplex. It may not be the case in your situation, but don't assume anything.
I would really like to understand how this could ever be the case...
