The relationship is not easy to quantify, and even harder to predict how adding more of a resource will affect meeting your goals. IBM marketing has some tools that will do a credible job of answering your questions. Check with your business partner or friendly IBM rep.
With ample main (a zero demand page in rate) and applications well tuned to exploit main, you might see reductions of upwards of 20% of total CPU consumption in I/O avoidance alone. You might also see some reductions in batch clock times ranging from just measurable to drastic. "Well tuned" means sequential batch with maximum block sizes and optimal buffer sizes, and onlines with very high buffer lookaside hit rates (98% or more). Sorry, but I have zero experience with WAS. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Craig Dudley Sent: Wednesday, August 02, 2006 9:57 AM To: IBM-MAIN@BAMA.UA.EDU Subject: CPU usage for paging <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> X-Mailer: CTM PowerMail version 5.2.3 build 4406 English <http://www.ctmdev.com> MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Hi, I am looking for the RMF report(s) where I can find out how much CPU time my system (2066-0A2 w/8 GB) to perform paging. I am trying to determine how much CPU I will "get back" if we buy more memory. WAS on z is involved ;>) Thanks -- Craig Dudley Systems & Communications Sciences, Inc. 244 Poor Farm Rd.
