Well, if the server's CPUs are idle and the machine
is starting to hog itself, one can
suspect something bad going on.

Basically, I'm wondering if I'm already on the edge of
performance capabilities of this machine/configuration, or maybe
there's some abnormal behaviour happening (which
could be noticed by somebody from this mailing list, hopefully).
In particular - could someone tell me if those iostat
values can tell if I'm close to upper performance boundary
of fast SCSI (Ultra 320, 15k RPM) disks?
