Ed, In my opinion, you're choosing the wrong feature to try selling ILE. There certainly ARE performance reasons to pursue ILE, but generally, performance gains will be modest. Simply buying a newer model of iSeries will take care of the performance issues, while lowering your operating and support expenses...... (Power, heat/air, etc...) No, the real gains to be had from ILE is in modularity. Write a useful function once, then use it everywhere... Think of this, versus the standard approach, where you grab this subroutine from on program, then that calculation from another, and so forth. In the end, you never know how, when, or where a particular function is being used. The challenge of bringing change to a programming staff is huge, and fear of change often brings out the worst in people. This is never an easy thing to do, but it often holds great rewards for the shops that break through. Modularity in software design has been a hallmark of nearly every language developed withing the last two decades, so it's hardly anything that could be called "new". For that matter, ILE is more than ten years old, and yet it's still called "the new stuff".

Doc, this should be fairly easy to roll-your-own on. and you could modify it to use customer data/apps which makes selling the case alot easier.

Nobody's looked into this? Nobody has even mentioned any anecdotal evidence. The reason I ask is this-- I'm trying very hard to push my client into ILE. (Their entire codebase is OPM.) They're fighting with the Cone of Fear argument ("We've never done that before."), so I need to have some sort of quantifiable argument. That sort of thing takes time. I was hoping that there was some sort of rudimentary analysis that someone had done, just to see if I should even bother with it-- if the speed increase is dinky, then there's no point in spending time on it.
