One thing I've used in the past that improves Realtek throughput is forci=
ng=20
the media type and duplex setting on both ends of the connection.  Autode=
tect=20
in the 8139s seems to be unreliable at times.

In my testing here I can get upwards of 1100kBps over 10baseT as long as =
I set=20
both ends to full-duplex 10baseT/UTP.  (This is from a 5.0-DP2 box to a=20
4.5-RELEASE box, 8139's on both ends; scp and nfs show about the same=20
throughput.)  iirc, Craig was seeing closer to 800kBps.  I'm trying to fi=
nd a=20
patch cable (or a crimper) to try 100mbps.
