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?

Demystifying Virtual Capacity, Part I

This is another contribution. Here is the link http://ibm.biz/demvirtcap01

Abstract: When we enter in the realm of virtualization, performance related concepts and terms must be revisited: we move from the fixed capacity of physical machines, to the variable capacity of virtual machines. Which are the factors this virtual capacity depends on? How does this virtual capacity depend on those factors?

Currently I'm working in the Part II. I hope it will be ready soon, very soon.

I hope you like it and, please, give me feedback!
