Often when my machine has load is 2 or higher it becomes very visible

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?
Not guaranteed, but it has worked for several people in the past - try
rebuilding your kernel with the SCHED_ULE scheduler, instead of the
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.
