70-100 does not seem to go as quickly on an OS/400
box versus Solaris.....my guess is that the MI layer
is handling work management tasks very cleanly. Also,
most AS400 models have ranges where you can expand
CPUs/memory/disk without having to swap out physical
hardware unless you reach max for that range. In the
SPARC environment, you'd likely have to swap physical
hardware out for a new model much sooner.
