With several ports or after enabling multiqueue, we need to assign efficiently the queues to the PMD threads. This can be done manually for well known VNFs and traffic, but an automatic assignation (rebalance) can also be triggered by openvswitch. This is done with the following command: # ovs-vsctl set open_vswitch . other_config:pmd-auto-lb="true" The rebalance interval shall be set with: (defaults to 1min) ovs-vsctl set open_vswitch . other_config:pmd-auto-lb-rebal-interval="<interval>"
The commit that adds that feature in OVS is included since v2.11.0. Assigning to OSP
