Windows 2003 file transfer rates

We have been playing around testing our network throughput. And it seems that
we have an awful performance rate.

Windows 2003 (U160 hard drive) > transfer via Gigabit > Windows 2003 (U160
as well)

File test, 2-3GB ISO's

Results, 200mbps or less, on Avg, 100-125mbps

Ive been looking around for tweaks, but none of them seem to have any effect.
TcpWindowSize, TcpAckFrequency, Tcp1323Opts, etc.

Anyone else seeing results like this, Im almost postive that we should be
seeing at least double the results.

Additional Info
Both boxes are Windows 2003 Server Standard R2

We are just transfering via file shares, not ftp.
