Increased efficiency of network
processing on Hyper-V hosts
Without VMQ
• Hyper-V Virtual Switch is responsible for
routing & sorting packets for VMs
• This leads to increased CPU processing, all
focused on CPU0
With VMQ
• Physical NIC creates virtual network queues
for each VM to reduce host CPU
With Dynamic VMQ
• Processor cores dynamically allocated for a
better spread of network traffic processing
Integrated with NIC hardware
for increased performance
• Standard that allows PCI Express devices to
be shared by multiple VMs
Virtual Machine
VM Network Stack
Synthetic NIC
