I also use topas, but our cpu's run at 60 to 70 % at Expire inventory
and DB backup. So even though it shows we have CPU left would 4 cpu's
divide it out and make these processes run in a more acceptable time.
>From 6 or 8 hours for 900000 items to say 2 or 3 hours. Nothing else is
running for 2 hours when these start

The one I use here to monitor CPU usage in AIX is command called Topas
