Well without any tuning of any kind here I get 7MB/s copying a 357MB = file
from my laptop to my server on 100baseT, so going to 1000baseT I = would
expect a 10x speed improvement.

You guys aren't getting anywhere near that kind of thruput so it's =
obvious to me that both you guys have a serious bottleneck somewhere. =
Personally my guess would be disk speed.

     Mike's setup may have other factors that hurt it.  Maybe it's his =
network adapters, poor drivers, or the operating system tcpop =
implementation.  He should probably provide those details.

     At my home without jumbo frames using a 32-bit PCI adapter on a =
desktop talking to a laptop with a PCI-E chipset I see 17 MB/s.  I can't =
try jumbo frames because my switch doesn't support them.  Between two =
32-bit PCI desktops I only get 16-1/4 MB/s.

    wow, that sucks, I would have expected more like 70MB/s with =
