Since Mhz and MIPS are such misused values, I prefer to run the same program on old and new engines to compare the performance change. I use an old FORTRAN (no flames please) program that computes pi to 5000 places. A boss once needed something to see if the vendor really did upgrade our processor, just after our Performance and Capacity Planning group was disbanded. So on an idle system, this just gets into memory and runs with a high Total/Virtual CPU ratio. On my z890 IFL, 20 iterations takes about 8.571 sec virtual, 8.578 sec total and 8.944 sec elapsed time.
Find a favorite program that is repeatable and keep using that to test the speed of your engines. But all numbers must be taken as relative and with a big grain of salt. /Tom Kern /301-903-2211 ------ Original Message ------- From: "Roach, Dennis" <[EMAIL PROTECTED]> Subject: Re: zSeries IFL speed rating I have been asked to determine the improvement of an IFL on a z9 BC over a z900. Mhz is something the people being presented to understand. It does not compare to the same speed on say INTEL.
