Hello. Just several questions about setup you are running.

1 - What is NUMA topology on your host?
2 - If there is NUMA topology, how PMD threads are spreading across NUMA nodes?

Best performance might be achieved if all PMD threads (as well as all vCPU pinned to VMs) are located on a same NUMA node.

For more detailed information about performance tuning please refer to https://github.com/openvswitch/ovs/blob/branch-2.6/INSTALL.DPDK-ADVANCED.md
