Yes, I am using MSI-X, and I pin the interrupt handler to one CPU (CPU#0 in my particular case). Then I use taskset to pin the NPtcp process to a CPU in a different package (CPU#2 in my system). BTW with these same systems, I am getting up to ~1150 MB/sec of throughput with DDR mem-free Arbel, as measured with NPtcp. > 2.
