May you share me with your performance results (including BW and latency)on vhost-net and how you get them(your configuration and especially with the affinity settings)?
My macvtap zero copy is incomplete, I am testing sendmsg only now. The initial performance is not good especially for latency (zero copy vs. copy). I am still working on it to find out why and how to improve. That's the reason I am eager to know your performance results and how much performance gain you have seen. Since your patch has completed. I would try your patch here for performance. If you have some performance results to share here that would be great. Thanks Shirley
