You're running 1,700 jobs concurrently? What are they doing? How "big"
is a model 550? We have a z9BC model V02 (2 processors) and month end
always pegs the CPU.

Well, this was looked at in 2004. However, at that time (and that now
ex-) management really wanted an "Windows only" environment and only
thru in the iSeries in an attempt to look even handed. When we (Tech
Services) showed all the submerged ice burgs in that. And the fact that
the vendor hawking the Windows solution could not answer our questions,
that died. Of course, we (Tech Services) are still held in disrepute
because we were not "team players".
