ROTFLMAO MIPS? Then you quote MSU? If you are going to use LSPR data, why not quote ITR? MSUs have been altered by IBM marketing to give the "technology dividend". And you are totally ignorong the number of processors. It makes no sense to try to calculate the CPU utilization on one system compared to another by taking a ratio of the total throughput when one has 22 processors and the other has 3. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
