For my patches using the xdp_redirect with virtio-net showed no measurable difference from running just the straight XDP_TX in the PPS column. However virtio_net XDP_TX was quite low to start with (and I was mostly just looking at functionality so I don't recall if there was a CPU usage hit) so I expect on ixgbe to see a difference. However I have plenty of cpu overhead to consume on the 10Gbps card so it will likely just be a CPU % cost not a PPS cost. I'll bother Alex about the 40Gbps cards ;) Anyways, I'll put it on my list to rerun. But like the xdp generic pieces it wont be for a couple days until I get around to it. Sorry need to take care of a few things first. Thanks, John
