I had problems when I first installed 4.0 because the xl0 was defaulting to half-duplex. The fxp0 in the other system was running full-duplex through its switch. Adding the "mediaopt full-duplex" in rc.conf was required to solve the problem. Make sure both machines have the right ip address for each other so that reverse DNS works. That seems to be the most common reason for a transfer that slow.
