Have you talked to Innovation Data Processing yet? If not, then you should -- the vendor should be your FIRST point of contact when you have questions about products they provide and support.

I found a 2013 Share presentation on IAM at IAM: Imprvoing Transaction and Batch VSAM Applications. Have you looked at the IAMINFO output (suggested in the Share presentation)?

It is entirely possible that you won't be able to improve CPU consumption for this application -- but the vendor would be the one to tell you if any improvement is possible.
