Sure, if someone can tell me what to do. I know even less about linux than I do about freebsd. :) First thing that came to mind: sysctl -a | grep -i time kernel.sched_time_avg = 1000 kernel.timer_migration = 1 kernel.sched_rt_runtime_us = 950000 kernel.hung_task_timeout_secs = 120 fs.lease-break-time = 45 dev.parport.default.timeslice = 200 dev.parport.default.spintime = 500 net.core.xfrm_aevent_etime = 10 Also this looks promising from /proc: http://people.freebsd.org/~dougb/timer_list.txt Doug -- Improve the effectiveness of your Internet presence with a domain name makeover! http://SupersetSolutions.com/ Computers are useless.
