That's a nice presentation, but I thought openbsd went way past 300Kpps, that was the same value I was getting 5 years ago and some serious optimizations have happened since than 5.0 introduces msi which might help in cases of shared interrupts. some interrupt stuff is streamlined and in 4.9 and 5.0 many ethernet cards get rid of certain extra work in the interrupt loop (locking, etc) that isn't necessary. -- There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely games. - E.
