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:
