That is with 100HZ kernel on PIII 500MHz or Sempron 64 2800+ Put kern.hz=1000 in /boot/loader.conf to kick it up to 1000Hz, that should improve the accuracy a lot. The optimizations in the url someone else posted should probably be integrated into FreeBSD, but moving to a higher Hz setting is a necessity in either case. Mike "Silby" Silbersack
