RE: Security level 50

Good news!  Going back to SecLvl 40 ought to be a snap.  If you have
good performance data just go down to level 40 for a month and then back
up, if there is truly a 10% performance hit it should be obvious.

One of the guys used to work with the iSeries at IBM.  I'm not sure to
what capacity.  I haven't had time to flesh out his knowledge of how
security level 50 would effect performance.

Really, it's not about performance problems -- it's more about the
suggestion that performance might be better if we weren't at 50.  We run
a pretty big iSeries server and we upgrade it when it doesn't meet our
run-time windows or threatens to do so.  We've had long stretches of
time where we've run with ASP at 80-90% of capacity without worrying
about performance, and we've had times when we've tuned the heck out of
the system and it hasn't been enough.

I'm trying to anticipate a time down the road when growth and contention
cause batch jobs to run too long, and some wise guy says "didn't those
guys say that security level 50 slows down the system?"  Then I'll have
to prove them wrong or back down to 40 or 30 along with a host of other
tuning stabs in the dark.

It's seems like the list is saying either:

"I've never seen a performance degradation"  or "IBM said there could be
performance degradation, but actual results may vary depending on your
system and applications"

        Are you experiencing performance problems?  If not then I think
it's
pretty safe to say you can ignore the claims.  It sounds like the person
that brought you to security level 50 would likely know a lot more about
it.
Quite frankly the very thought of trying to accomplish it with my system
leaves me shaking.  I can't even imagine accomplishing it without some
sort
of service interruption.

Don't you just love these general ideas with no backup material?
