Hear! Hear! I cannot count the number of times I have overseen an upgrade to a processor, and had management complain that throughput, or response, had not improved. Most of the time, I had already told them that there was an I/O bottleneck, tape-drive contention, scheduling, etc. issue. But, they told me to upgrade the processor, anyways. Yes, we usually needed the processor, but the other issues would usually give us a better improvement. Empirically, I have seen that the I/O content of most processing (online or batch) has increased since the early 1980's. This is especially true if you are using DB2. I have had a lot of one-hour+ jobs using less than 2 minutes of CPU. We call these I/O-bound jobs. So, even if I double the speed of the CPU, I have improved these long running jobs by one minute. Microseconds don't count, any more. - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
