You can use 10Gb NIC cards, but when you assign vnic to each VM, the traffic is directly goes through VNIC, and not through OVS. The observed behaviour is that if the traffic goes via OVS, you may not see 10Gb speed, and it varies. What is the need of sending traffic via OVS. Is there any decision making happening at OVS side.
