I used IAM, Rocket's Product and BMC Batch Optimizer. All of them provide
great benefit in reduced run time by reducing I/O. My favorite isBat/Opt
Standard Edition. Why, because it is FREE and easiest to use. Also, it
provides stat reports that identify files that are read one recordper open(bad
program code) even with proper buffering.

Subject: Re: Anyone using Rocket Software Performance Essential
I used it for 30 years until I got laid off. Yes, it started as VIOplus
from Softworks and then it went to EMC then Rocket. It saved incredible
amounts of time as we were a huge VSAM shop. I tested a few real VSAM pigs
and ran jobs turning off VIOplus (perf Essential now) and jobs went from 1
hour 10 minutes to 18 hours. Actual time. There was no way I could
possibly sit down and figure all the jcl changes to tune the VSAM file
access to get this kind of benefit. I haven't touched it since 2012 but I
would assume it still helps alot with VSAM and Qsam.
