Your optimization will help the RX enqueue side, but the bottleneck for CPUMAP is the remote CPU dequeue. You should still be able to see that RX-side performance improve, and that should be enough (even-though packets are dropped before reaching remote CPU). I'm not going to ask you to test scale out to more CPUs. -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
