VMQ

VMQ (Virtual Machine Queue) allows traffic inbound to a particular virtual adapter to bypass much of the network processing stack of the management operating system. When a virtual adapter (legacy virtual adapters are not eligible) connects to the virtual switch, it will request a queue from the hardware adapter hosting that switch. If a queue is available, it will be assigned to that adapter. Traffic inbound to that virtual adapter will be marked by the hardware so that the management operating system will not need to inspect the packets to determine which virtual adapter it is intended for.

VMQ is a very useful technology and can have a measurably beneficial impact for virtual adapters in Hyper-V Server. Before you begin enabling it, ensure that your physical adapters actually support it. You'll also want to determine how many queues an adapter supports in order to prioritize virtual adapters that will have VMQ enabled.

To begin, enable VMQ on physical adapters that host virtual switches...
