Path-length is one influence factor. Under hybird vif-driver, packet traverses through 2 extra linux bridges, to get to destination VM.
Also, we strongly suspect 2 extra veth device pairs might be another influence factor. As shown in our test, the performance of veth device is not as good as ovs patch port.
Thanks Rick for the advice.
