Rather than giving up in the face of this kind of relentless pressure to get things done faster, Guerrilla Capacity Planning facilitates rapid forecasting of capacity requirements based on the opportunistic use of whatever performance data and tools are available in such a way that management insight is expanded but their schedules are not. A key Guerrilla concept is tactical planning whereby short-range planning questions and projects are brought up in team meetings such that management is compelled to know the answer, and therefore buys into capacity planning without recognizing it as such. Once you have your "foot in the door", capacity planning methods can be refined in an iterative cycle of improvement called "The Wheel of Capacity Planning". Another unique Guerrilla tool is Virtual Load Testing, based on Dr. Gunther's "Universal Law of Computational Scaling", which provides a highly cost-effective method for assessing application scalability. | | | Features: | |

Great coverage of Capacity Planning and Performance ManagementAug 24, 2008
Very readable coverage of Capacity Planning and Performance Management. Doesn't presume any previous knowledge, but doesn't talk down either. Several good chapters talking about queueing theory.
A great practical handbook.

Who does this better?Mar 15, 2007
I've read the other reviews and they seem to ignore the "Guerrilla" concept. The fact that scientific analysis is ignored and decisions made on perceived knowledge in most companies for me is the key to the book. Excel is a great way to get the performance point across even with precision errors. Getting management buy in is 99% of the process. GCP makes that argument simple. Read this book and get the word out. Performance is not linear!

 Enlightening, however ...Mar 11, 2007
First of all, this book was worth the money I spent on it. I came away from reading this book with a clear understanding of the differences between speed and scale, and with a system for modelling the scalability of systems in general.
However... really all of this value was in the first quarter of the book. I read on and read on looking for further conceptual gems but they weren't to be found.
I guess that books are "meant" to be at least a particular length, but this one could have been much shorter and more concise.

a gem and a keeperMar 10, 2007
With Wall Street analysts drives the planning horizon, Management prefers getting a sense of direction quickly and repeatedly, instead of belated precise readings of compass bearing. It is in this agile and opportunistic spirit and philosophy that Dr. Gunther introduces Excel, linear regression, and 2 parameter scalability models into the performance analysts' tool chest.
Excel is ubiquitous. It is also easy to use. Use it. If there is sufficient time, better tools such as R or Mathematica can be used to cross-check Excel results. Similarly, linear regression is another tool in the agile performance analysts' tool chest.
Two chapters I have not seen presented elsewhere are the virtualization spectrum and effective demand. In a prior job, having virtualization spectrum chapter available to me would have save me much grief with an workload manager. The effective demand makes another useful capacity project tool to keep handy.
The best part is Dr. Gunther's 2 parameter universal scalability model. It can be immediately used to frame your load testing results to project application scalability. This alone is worth the cost of the book and admission to his classes.
Conjecture 4.1 on page 65 on 2 parameters are necessary and sufficient for scalability model based on rational functions are an interesting open questions. Given that the denominator is a quadratic equation with c = 1, we should be able to argue that it behaves like a parabola, except with c = 1, we won't get into singularity/infinity. For more details, please see Dr. Gunther's blog at

A Solid WorkDec 19, 2006
Alright I finally got the book! As promised a proper review.
This is the third Gunther text I have purchased. I believe his work is unique and is filled with interesting ideas. Some of the ideas he takes from his previous works but overall it is a nice compliment to his current bibliography.
If you are interested in performance tuning and capacity planning this is a good purchase. I highly recommend it. Plus I love the little "Guerilla Manual" that is included in the back sleeve of the work.
