Improving Ghostcasting (unicast) speed over 10GbE NIC

Hello All,

I have a server connected directly to client over 10 GB NIC (at both ends) with Cat6a cable.  No switch is currently in use. Ghostcast server is running on the server and the client is PXE boot to Ghost64.exe to kick off unicast.

Image is Windows 7 (64 bit) captured with Ghost32.exe. 

When imaging the client on GhostServer UI, I see speed range from 1100-1200 Mb/min .

Any suggestions on improving imaging speed on 10GB ethernet is appreciated! 

Thank you.
