Hmmm... I've been running WebSphere for some time now.  I've currently got
over 7500 seconds CPU time (not a lot, I know, but bear with me) between my
server instance and the admin instance since my last IPL.  Total temporary
address space usage?  .009% (yeah, two zeros).  By straight extrapolation,
(and this assumes that ALL address space usage so far is WebSphere), at 100%
CPU utilization for WebSphere I'd get to 90% temp address usage in...
75,000,000 seconds, or about two and a half years.

So why is my usage so low compared to other quotes?  I can't be sure, but
one glaring difference is that I don't use SQL at all.  All my webserving is
done via messages to RPG back end programs.  I'm no performance expert, but
I think you might want to do a little more checking before pinpointing
WebSphere as the sole problem.

Joe
