You still have to pin the nginx threads to whatever your limited set of RSS CPUs are, or the benefits aren't really there. I'd rather we just get librss defined in FreeBSD-HEAD and then have nginx "know" about that for FreeBSD. It already has to know about the linux way of doing it and it has to be conditional on it running Linux. So it's not a big stretch to need to know about FreeBSD. I haven't forwarded anything on to john yet, I'm busy trying to debug the NUMA enumeration/configuration stuff i'm working on and why jhb's patches break that for me. :) -adrian
