I can recommend a series that is currently being written on Hyper-V Networking Optimizations by the hand of Cristian Edwards who is Premier Field Engineer in Microsoft Virtualization at Microsoft.

Since Hyper-V R2 network optimizations were not only supported at the host level but also in the guest. If you roam the Internet you will see a lot of talk and confusion about whether to configure things like TCP Chimney Offload or when and how to configure Virtual Machine Queues (VMQ), Receive Side Scaling (RSS) and Jumbo Frames.

I am very glad I found this great source and we might consider this the definitive guide to configuring the Hyper-V networking optimizations.

The series consists of six blogs (five of them are finished):
