Does that include OMVS fork()? Seems like overkill given that
some jobs may do copious forks.
OMVS can produce a lot of SMF records. I did some testing on a short
shell script, and 1000 iterations of a loop produced about 28,000 type
30 records - around 200 records/second. The good news is that the
records are likely small with very similar data, so the facilities to
compress SMF data should handle it nicely.
I wrote up the testing here, and it gives some idea of when separate
address spaces are used and SMF records written:
