for a virtual router, yes ! (think about a synflood attack for example)
Also, for latency, applications like redis really need it

Where are you seeing that ?
AFAIK, ovs (without dpdk) and linux (bridge or routing) are both limited to around 1,5-2 mpps for 1core (any framesize).
Linux kernel devs are still working to improve this, but it's far from the speed of dpdk.

Thats impressive, but maybe a very special case? 64Bytes frame size is very
it does not really matter in real live?
ovs+dpdk is also slower than linux on other frame sizes...
