Home -> Community -> Mailing Lists -> Oracle-L -> RE: does CPU usage matter when scaling?
Ryan,
Take a look at "Why you should focus on LIOs instead of PIOs" at www.hotsos.com/e-library. If you have access to the book "Optimizing Oracle Performance," check out chapter 9.
If an application is written not to crash into some kind of serialization barrier (latch free, enqueue, etc.), then the thing it *should* get stuck spending most of its time doing is consuming CPU service. Applications that consume less CPU service scale better than apps that consume more. I would then say that it's FANTASTIC that your software engineers are looking at CPU consumption as they design, build, and test their code.

The softwrae engineers are measuring CPU usage. I usually ignore this and dont care about that value. I dont have any docs on it. anyone have any docs on this? or am I wrong?
