Use "systat -vm 1" to check if there are <100% disk usage during these periods.
Also check if your system is swapping a lot - that would indicate a ram
shortage. KDE is huge and requires quite a lot of memory, if your system starts
swapping then you would probably find KDE grinding to a halt.

I am not aware of any way to change the IRQ's. I certainly have never had to do
it.
