NetQueue and Networking Performance

NetQueue takes advantage of the ability of some network adapters to deliver network traffic to the system in multiple receive queues that can be processed separately, allowing processing to be scaled to multiple CPUs, improving receive-side networking performance.

The NetQueue balancer in ESXi uses load balancing algorithms to effectively utilize Rx queues in the physical NICs by managing vNIC and VMkernel adapter filters.

You can enable or disable different types of Rx queues. For more information, see the esxcli network nic queue loadbalancer set command in the vSphere Command-Line Interface Reference documentation.
