There is an APAR that provides a new setting (KCINDEX=N) that you use (after
the first time you start zosmf), that keeps the i/o's down to a much more
reasonable level. Our clients that have small single frame systems (z13s,
z14-rz1), find that it cuts the startup time by almost 40%.

@Kurt - thank you for the qualification - "...but z/OS software will
continue to be serviced using PTFs and therefore using SMP/E".
I hadn't read or heard that until now. Its good to hear that that is the
case.

z/OSMF can create an extract of the migration information (now called "upgrade"
instead
of "migration") from the z/OSMF workflow (either z/OS 2.2 to z/OS 2.4 or z/OS
2.3
to z/OS 2.4 - whichever one you import from GitHub or both). It's in HTML
format
and quite readable with links to the diffe

I have been investigating this exact issue. Looking at SMF 92 records,
it appears that z/OSMF opens, reads and closes the same files

I thought my situation was bad - it only takes 30 minutes at 100% CPU on my
test system to bring up z/OSMF.
Does anyone run this on a production system?

Does IBM plan to hand out zIIP engines for free to allow sites without access
to them to run z/OSMF with reasonable performance? We have zIIPs, but just for
the heck of it I tried starting z/OSMF on a non-zIIP LPAR. It took 8 hours to
initialize, driving the (admittedly very small) LPAR at 100%
