I made some tests with quad core CPU: netstat shows: input (em0) output packets errs bytes packets errs bytes colls 533738 0 32024280 181592 0 10506120 0 526035 0 31562100 181580 0 10508266 0 524260 0 31455600 181683 0 10509310 0 524264 0 31455840 182385 0 10550374 0 pmcstat results - http://89.186.204.158/hwpmc-p4-quadcore.txt not sure if they are correct because the system livelocked during pmcstat run, so I did cold reboot. if_em is compiled as module here, so grpof from if_em is at the end of the file. Quite surprising quad core is slower in this benchmark, and I'm still trying to find what is different if we do not count the cpus :) -- Best Wishes, Stefan Lambrev ICQ# 24134177
