Re: "Sticky" mouse pointer on machine with high load
Not guaranteed, but it has worked for several people in the past - try rebuilding your kernel with the SCHED_ULE scheduler, instead of the make sure you have quite new FreeBSD 7-* branch, as it was quite improved few months ago. you may try to tune it up by changing kern.sched.interact sysctl in short - higher value - interactive processes gets better scheduling SCHED_BSD4 scheduler. Although ostensibly its benefits are more obvious on multi-processor machines, it does often seem to fix this mouse lag issue that comes up from time to time. It has been discussed on the list several times, so you might find some interesting further reading if you search the archives.

"Sticky" mouse pointer on machine with high load
Often when my machine has load is 2 or higher it becomes very visible that mouse motion isn't smooth. Mouse moves in a series of quite long jumps. I believe this effect is especially pronounced when some applications read/write a lot of files. My understanding is that this is because signal from mouse gets stuck in the fifo somewhere and not processed by x-server in time. Is there any solution to this problem? I never saw such problem on Windows though I didn't touch Windows PC for many years now.
