I changed the nice from 0 to 1 and it didn't make any difference.

Thanks for the tip. Htop does seem to be an improvement over top,
although it is impossible to read the legends at the top and the bottom
of the display because the letters are black on dark green. Maybe
there's an option to change the color scream. I'll man-page it. Another
option I need to make it sit still. Trying to read it is like watching
a five-year old in church.

The more I poke around the more I think the problem is that the CPU
speed is being throttled back by something in Linux. I looked in the
GUI for power management and found nothing. I don't understand why my
MHz applet stays at 800 even when Scribus is trying to do something
that must certainly be CPU intensive. I mean, occasionally it does go
to 2.0 GHz briefly, but usually it stays at 800 even when I am
patiently waiting for Scribus to do something.
