But my testing showed significant slow down when calling an ILE
program vs. an OPM one.

I know. That's generally related to activation group creation but could also be due to the number and size of any service programs referenced. What was the activation group setting on your called program?

My comment was more directed to OPM CALLs which I had thought was apparent from the reference to CPF but I see how the mention of ILE may have confused things. My recollection is that ILE external program calls were SO slow that significant work was done to improve the CALL code path and as a side-effect OPM call performance was also improved.

My real point is that you can't just accept things that may or may not have been true some releases ago, nor can you discard a technique because someone says it's slow without also knowing exactly how it was tested or determined to be slow.
