Hi, if you're feeling brave enough and you can test/experiment with pf you can download openbsd kernel with experimental MP support from here http://kosjenka.srce.hr/~hrvoje/zaprocvat/smpfbsd SHA256 (smpfbsd) = e95e94190a0e52de7690b3278cfab14985817089e7a53615cd2599420593b32c this kernel is compiled with option WITH_PF_LOCK and NET_TASKQ=4 before you download it please backup your active kernel so if something goes wrong you can put it back .. cp /bsd /goodbsd cp smpfbsd /bsd reboot if something goes wrong at boot prompt before kernel starts to boot you can boot old kernel with command - boot goodbsd i'm running this kernel for few days and i'm hitting pf, pfsync and pflow quite hard and it seems stable :)
