Demystifying Performance

I've always felt attracted to computer performance subjects: throughput, response time, sizing, bottlenecks, usage, capacity. I've not always seen clear, understandable and knowledgeable explanations on these subjects. With the arrival of the virtualization even more complexity is introduced: terms that represented constant values, like the machine capacity, gets blurred. What can be said about a virtual machine capacity if it is no longer a fixed value and may change from this hour to the next?

The Sizer Advisor

Here are the links to two documents I authored on sizing, and a brief description:

The Sizer Advisor, part I ( http://ibm.biz/sizadv01): This presentation expose ten elementary advices for sizers, the people dealing with sizing, sizing guidelines and related topics. Advices are generic, not particularly related to any specific sizing. Beginners should find it interesting, and experts may extract and reuse any slide for teaching their own trainees.
The Sizer Advisor, part II ( http://ibm.biz/sizadv02): This presentation is the second part of The Sizer Advisor series. It exposes ten additional elementary advices for sizers, the people dealing with sizing, sizing guidelines and related topics. Advices are generic, not particularly related to any specific sizing.

I hope you like them!
