Dr. Merrill's book which is in this library can be very helpful. I don't have MXG. I have the IBM performance tables https://www-304.ibm.com/servers/resourcelink/lib03060.nsf/pages/srmindex. That's where I got the SU/second numbers in my OP. My question really was whether the SU/Second machine-to-machine ratio was the first factor to be looking at, and was I using them correctly, and I guess that is so because no one has said it is not. (It's just that beyond that, "it depends.") > Second, what is meant by CPU Performance question? The question distilled to its essence is "if job X takes n CPU seconds on box A, then will box B have enough horsepower to run 1000 jobs very much like X every day, and how much CPU time will they use?" > There is not, imho, not a one answer to a general question. It will depend on hardware, software and user perception. Yup. But management wants (IMHO understandably) a go or no-go answer. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
