We've been quite surprised this year on the effects engine speed can have. We have never taken it into account before when upgrading. <br /> Our z10 608 to 512 "upgrade" was a complete disaster. More MIPS, but just didn't work performance wise. <br /> Our z10 609 to z196 704 (on Sunday) has been an amazing success. Less MIPS, but much improved performance. <div>&nbsp;</div> If only we understood how to predict what difference engine speed changes would make to our performance!

Hello Patrick! (Not sure which one you are.) :-) Someone else complained there was no "happy ending" in this post. I think they're right. :-) For various reasons I'm inclined to ask for a CPU Queue Time number in SMF 30. I'm not sure how feasible that is. Nor quite how valuable that would be. My guesses are: 1) Pristine CPU Queue Time is difficult, and 2) It would be really quite valuable.
