>I don't think there's much to be gained by treating Mr. MacNeil's rhetorical flourish as a research finding. Gee. Thanks for the respect. It was not rhetorical. I did empirical research with STOBE. Have you? Also, try -PEEKing with OMEGAMON, and finding where the time is spent. Yes, user code is written to handle business rules, but how much of system services are done by user code? Check, then b*tch. <SNIPPAGE> OK. I write BSAM code using low level interfaces. As well as TCP/IP and UDT. But I work for an ISV. So my code will be part of that large amount that is not written by the customer base. However, in a prior life, I have done VSE to MVS migrations, banking and scientific software. As a result, I've seen a lot of shops that did their own in-house development. I've seen a lot of code written in Assembler, COBOL, RPG, FORTRAN, PL/1 and 3rd GLs besides CLIST and REXX. So, based on some snap shots of some code from some customers we can say that the users are only responsible for 5% of the CPU usage? I think I have a healthy skepticism here. But I've been proven wrong before.
