The out of tree module of OVS 2.4 doesn't support VXLAN GRO (which would be the source of the performance improvements that you are looking for). You'll need to either use the upcoming OVS 2.5 release (currently in testing) or the upstream module with a newer kernel.

What kernel are you running this on (both sender and > receiver)? Is this the OVS out-of-tree or upstream module? _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
