Not always or even very often. For example, Solution Editions are outside
scope (unless they have EC3/4-compiled COBOL -- rare but possible), and so
are zIIP MSUs and non-peak MSUs.

I'd offer this advice instead: Automatic Binary Optimizer (ABO) is likely
attractive if you have at least "non-trivial" peak COBOL workloads compiled
with Enterprise COBOL Version 3 and/or Version 4 in at least one z/OS
"pricing-plex"(*) in your enterprise, and if you are not shifting most or
all of those peak COBOL workloads relatively soon (or sooner) to Enterprise
COBOL Version 5 or higher compiled code. ABO can also be attractive if you
have CPU-bound batch COBOL workloads (compiled with Enterprise COBOL V3
and/or V4) and if you are looking to reduce batch processing times, and/or
in a few rare cases when elapsed transaction times are critical (e.g.
credit/debit card authorizations) -- again assuming you are not shifting
relatively soon (or sooner) to Enterprise COBOL Version 5 or higher
compiled code. Note that the EC3/4-compiled code can be vendor-supplied,
in-house, or both. All EC3/4 COBOL run-times count, including COBOL stored
procedures in DB2. Also take into account older COBOL code that is being
migrated to EC3/4 (or should be, or will be).

Sorry that's a bit wordy, but I think it's a reasonably comprehensive
summary in one paragraph. "Java bad" for these purposes? No, that's
oversimplified at least. Just focus on the EC3/4 COBOL (including
vendor-supplied) and its contributions to peak, to batch elapsed time, and
to elapsed transaction times. That's conceptually simple, too, but also
better advice in my view.

(*) This isn't *quite* right either. There are cases when less than a
"pricing-plex" is enough, but now I'm really getting into the weeds. :)
However, I'm tempted to put "LPAR" here for these reasons. "LPAR" is
certainly enough for a "merits investigation" standard.
