 Try to set scheduler's preemption threshold to large priority value,
 the default one is too low for cpu-bound application, and can starve
 other threads under heavy cpu load. for example:
 sysctl kern.sched.preempt_thresh=220
 
 On 7.x and 8.0 kernel, I always set a large value for my Desktop PC.
