We had a similar problem with Intel Etherexpress Pro / Summit 48i.
After some tweaking the link is OK ONLY when both sides auto-negotiate the
speed. Fixing a given speed on one side and auto-negotiation on the other
slowed down the connection speed by about 80% under "heavy" load.
I'd suggest trying to play with speeds / Duplex / Auto-negotiation settings.
You may want to have a look at tcpdump too... Maybe you have an ARP problem ?
Good Luck
