Tim:

I've been monitoring our JARMSRVD job all day and I've seen very little CPU
usage.  According to the SHOWPROC command, it has used about 17 minutes of
CPU time (job total, of which one process was responsible for 15 minutes)
over the last 3.2 days.  In rough numbers, that's just under 0.4% of the
CPU.  The system here is an A500-100-140 with 1.5 GB RAM.
