RE: Daily save reduced by 20 to 30 minutes since applying latest firmware, latest CUM, TR8, latest Groups -- MIDRANGE-L

I don't know that the normal saves without SWA will run faster, they might
but that was not the point of the PMR.

So can we "presume", that my full system save, which doesn't use SWA, will
run faster as well on the IFS?
I ask, because the IFS save time on our full system save takes as long
without running SWA as it does with SWA...

That PTF was developed as part of a PMR that was called in by a customer.
In that case it was only part of the fix, where a save operations in
an iASP grew substantially after a system outage. It turns out there
was quite a memory leak in the save software that caused a significant
amount of page faulting. The save time savings is by eliminating the page

faulting.

looking closer...
this PTF said it was improving the SWA on the SAV command...
my SAV went from 42 minutes to 11,
but also my SAVLIB went from 30 minutes to 13....

25% faster if you are using SWA.

If you use SWA, get this PTF installed ASAP.

latest firmware, latest CUM, TR8, latest Groups, My daily saves on
both Production and R&D LPARs has been reduced by 20 to 30 minutes.

Is anyone aware of any major performance fixes?
Has anyone else noticed save reduction times?
