We have 4G, not from recommendations, but from experience. CICS 5.x required
this.

Correct, CICS 4.1 requires 4G.

CICS TS 5.1 requires MEMLIMIT=6G, according to the doc:
http://pic.dhe.ibm.com
I do not remember that IBM has ever characterized its defaults as
'optimal', whatever that may mean without context. What it does try
to do---with, I think, reasonable success---is to provide defaults
that are innocuous in the sense that they do not give trouble for most
jobs most of the time.
My IEFUSI still prevents REGION=0M for all but STCs. Sort of worthless these
days on
95% of the systems, but I actually still have some small monoplex LPARs that
only have 1.2G - 2G, so the old region=0M and variable length getmain issue
is still a valid concern for those LPARs. Actually,

BTW SMF 30 also has the limit and how obtained in it. So you can see what
an individual job / address space can get at and why.
As one might imagine, the system control block also contains the source
of the MEMLIMIT:
