There have been some time since I've noticed it, but could just ask for help now. I have a Core2Duo E7400 (2.8GHz), with 2GB of DDR2.
My gnome-system-monitor applet ALWAYS shows half of the CPU meter busy... most of it by user procs, and some by system too.

I can't understand why, idle, my CPU is being used like that.
It used to be only shadowy dots in those CPU graphs, not a hole half!
Is there something I can do to further discover this? Or it's just... normal? =S
