I've noticed similair things myself.  Although I've not looked into it
in depth, but certainly things don't feel as snappy when the system is
really busy with the disks.

(I'd guess that pic0 pin 14 is the disk on your system)

If you could also check if the disks are busy, there's a list on the
bottom left of systat vm, or use systat iostat as well.
