Sorry for reposting, but I should add that my concern stems in part
from top reporting that 27% of the CPU is being used by users, and 73%
by system, which conflicts with the line item for paup, a user
process, which shows 99% CPU use. So I'm not sure if paup is using 99%
or 27% of the CPU:
This is not a conflict. There are no such thing as "user processes"
and "system processes". You are looking at different kinds of breakdown.
Cpu(s): 26.7%us, 73.3%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si,
0.0%st

What this says is that paup is using all (99.7%) of the CPU, and that
of this 26.7% is spent executing in user mode, and 73.3% is
spent executing in supervisor mode. Ordinary programs switch
the operating mode of the processor by making system calls.
The time allocated to the process is partly in user mode, and
partly in system mode. If you read the manual page for "time"
you'll get a little more information.
