[X4U] Ethernet Settings

OS X data transfer (server to Mac hard drive) is 20% slower than if the same
machine booted in OS 9 were to perform the same copy.
"ifconfig en0" reports full-duplex. It should be full-duplex.
Network Utility is not reporting any errors or collisions.
MTU is at 1500.
As I continue to investigate. I have discovered the server supplying files
is a Snap Server. Possible culprit?
