So I was able to achieve 70,000 pps sustained with an IMIX of UDP packets.
However when I run: sysctl net.inet.ip.intr_queue_drops
I see the number incrementing quite quickly, net.inet.ip.intr_queue_drops: 645011625 :)
Any idea on what I can do here? I booted the IP Input Queue to 3000, then 10000, and stopped at 25000 with no real results.
It could be that some of the traffic I'm generating is being dropped anyway.
Any opinions on whether or not I should use the traffic shaper? PriQ has always served me well with slower connections, but I'd be apprehensive about having queues that might not be optimized for 1Gb links.
