Hi, Charles:

The answer is, "It depends..." (on exactly how you coded the CALLs, etc.)

Please go to http:code.midrange.com and post your little benchmark programs source members there... and then, send an e-mail to the list that includes the URLs for each of your little example programs ... (generated by the code.midrange.com web page).

Then, we can take a look, and perhaps explain some of what is going on here.

Thanks,

Mark S. Waterbury

All,

I was doing some benchmarking on an unused 515 running v5r4, and I'm seeing some results that
surprised me...

5M 50M
OPM calling OPM 6s 62s Dynamic Program Call 12s 122s
Bound Procedure 1s 4s
--In the first case, an RPG III *PGM was calling another RPG III *PGM (which returned with LR =
*OFF). --In the second case, an RPG IV *PGM was calling another RPG IV *PGM (which returned with LR = *OFF).
--In the third, an RPG IV *PGM was calling a RPG IV procedure in a *SRVPGM.
Both of the called programs and the called procedure simply RETURN.
I'm a little surprise to see RPG III program calls performing better than RPG IV program calls. I
thought perhaps it was activation group related. Initially, I had *NEW calling *CALLER. I tried
changing both program to run in the same named activation group. That had no effect. So I tried
changing both to DFTACTGRP(*YES). That had a little effect, lowering the times to 11s and 110s.

Does anybody have a explanation?
