Ok, so I was doing a test just now and best transfer rate I could get over
gigE was 9mb/s.

I'm about to tweak some settings per the below but if anyone has any other
suggestions I would appreciate it.

The magical location for TCP settings in the registry editor is
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

We need to add a registry DWORD named TcpWindowSize, and enter a
sufficiently large size. 131400 (make sure you click on 'decimal') should
be enough. Tcp1323Opts should be set to 3. This enables both rfc1323
scaling and timestamps.
