I think this is not that big of a deal. Since this test is primarily about vlans and not performance, the absolute number isn't really that important. This is particularly true with UDP where for a given size I would expect it to either work or not. UDP also almost always has lower performance than TCP anyways because there are fewer offloads. I see that you still have a fixed set of sizes to try for UDP packets, did you look into detecting the MTU? _______________________________________________ dev mailing list [email protected] http://openvswitch.org/mailman/listinfo/dev
