Found one major issue - the systems where the issue is are z/OS 2.1 and the STEPLIB=none variable looks to have been new in 2.2. Reducing the STEPLIB and ISPLLIB solved things.

I am working on a project where the omvs performance on some systems is slower than one would like -definitely not sub-second. I'm looking for tuning suggestions. When under ISPF the elapsed time is more than double the elapsed time when in native TSO. Note that the OMVS environment includes STEPLIB=none but my guess is that the ISPLLIB may be the culprit when under ISPF - I just can't prove that (yet). Thanks for any guidance. Lionel B.
