If you've got any users at all, even just sitting there doing nothing
but still logged in, then nah, I wouldn't be worried. All GNU/Linux
boxes use just a little CPU at quiescence (maybe 0.5 to 0.8% per CPU), a
little bit more when you run top. I've seen top take up 1% or so,
depending on the speed of the CPUs and how often you tell top to sample
your resource usage. Also, you've got to do some X11 protocol processing
to facilitate the display of all that stuff that people are seeing (it
isn't much, but it's there).
What are the top CPU-using applications when you see the
5%-per-processor usage?
