A bit google-ing suggested stopping the 'Windows Firewall/Internet Connection 
Sharing (ICS)' service, which gets windows using the 'large send offload' 
feature and puts the TX up to around 50Mbit/second, which is a bit of an 
improvement.

With just the qemu devices on that server I get around 28Mbit/second TX and 
about 25Mbit/second RX.
