I sometimes use 

WRKACTJOB SEQ(*CPUPCT) then hit F5 a couple of times

This at least may clue what jobs are using the most cpu a any given
moment.

You might need to check on how much disk space you're using.

I am getting vague complaints from our users/developers that one of our
AS400's (a 270, v5r3) is "running slow".
I don't think it's a CPU problem, more like IO is getting thrashed. 
One Developer suggested that it may be QYIVRIPS. I did notice the
message "Attempt to download a current phone list was unsuccessful." in
it's job log, but I'm not too excited over that. 

What tools/methods are there for determining who/what is thrashing the
IO on the machine? 
I'd rather start this way rather than calling IBM, telling the vaguely
"our machine is running slow", and then imagining the IBM Tech's eye's
rolling back in his head upon hearing the question.
