Sending traffic from the kernel through an OVS port of type internal to a OVS-DPDK netdev bridge is slow because it is processed by OVS's main thread. This may also slow down PMDs, since traffic is sent to kernel interfaces via the send() API family.

To lift this issue, we have to change OVS interfaces br-ex (in Machine Config Operator), br-int and ovn-k8s-mp0 (in OVN-Kubernetes) from type internal to VDUSE devices.
