At the last hackathon, there was a lot of work done on profiling and optimizing the path through the network stack/PF; you'll see more about this at http://www.openbsd.org/papers/cuug2007/mgp00012.html (and the following pages). > What exactly is this queue?

The -ve is because it's a signed integer and has, on your system, exceeded the maximum value since bootup.. > net.inet.ip.ifq.drops=-1381027346 > I've put maxlen=256 and it seems to have slowed the count down. You might like to try bumping it up until it stops increasing (uh, decreasing. :-) And re-investigate when you get 4.2 (or make any other changes to the system).
