Every Computer Performance Book: How to Avoid and Solve Performance Problems 
on The Computers You Work With

Availability: Ready to download

This is a short, occasionally funny, book on how to solve and avoid application and/or computer performance problems. I wrote it to give back the knowledge, insights, tips, and tricks I was given over the last 25 years of my computing career. It shows practical ways to use key performance laws and gives well tested advice on how (and when) to do performance monitoring, cap This is a short, occasionally funny, book on how to solve and avoid application and/or computer performance problems. I wrote it to give back the knowledge, insights, tips, and tricks I was given over the last 25 years of my computing career. It shows practical ways to use key performance laws and gives well tested advice on how (and when) to do performance monitoring, capacity planning, load testing, and performance modeling. It works for any application or collection of computers because it teaches you how to decipher whatever meters they give you and how to discover more about those meters than the documentation reveals. This book covers the things that will always be true no matter what technology you are using. It will continue to be useful 20 years from now when today's technology, if it runs at all, will look as quaint as a mechanical cuckoo clock. There is no complex math required; yet it allows you to easily use some fairly advanced techniques. Simple arithmetic, and a spreadsheet program, is all that is required of you. Lastly, it helps with the human side of performance. It shows you how to get the help you need and how to present your findings (good or bad) all the way up to the CIO level.

    Prepare for Performance Improvement Buy this book, read it, and start to use it, before you need it. You will thank your lucky stars. If you build SaaS, or database-driven software, or embedded software, or firmware, or just about any product with software in it, eventually you are going to wonder why the heck it is so slow. Thank goodness Bob knows how to explain how to investigate. From the Four Tools of Performance to Bob's Performance Rules, this book is easy to read, easy to understand, and Prepare for Performance Improvement Buy this book, read it, and start to use it, before you need it. You will thank your lucky stars. If you build SaaS, or database-driven software, or embedded software, or firmware, or just about any product with software in it, eventually you are going to wonder why the heck it is so slow. Thank goodness Bob knows how to explain how to investigate. From the Four Tools of Performance to Bob's Performance Rules, this book is easy to read, easy to understand, and easy to implement. If you need to develop or test software under load or for performance, you should buy this book today and start to use it. There is another reason to buy this book now. If you work on an agile or lean team, you should buy this book for Chapter 3. Bob talks about computer systems, but he could be talking about people. Yes, he's talking about queueing theory and bottlenecks and Little's Law, but he's talking about busy-ness at peak and resource utilization. You can use this book to *measure* your team and prove to your managers why you should not multitask. You can use data! Bob also has a section on making friends with people so you can help changes happen. The book is easy to read and easy to understand and fun to read. Buy it, read it, and enjoy the beautiful pictures.

    This books is super useful for folks who want to get their heads around performance engineering. I would highly recommend it for every manager out there. It's short and to the point. Main concepts and touch points are explained in a very simple non-threatening way. The best chapter is chapter 3 - about useful laws of software performance. Yes, it's mostly about little's law and its variations. But it provides a good way to built an intuition around it.

Yes, it's mostly about little's law and its variations. But it provides a good way to built an intuition around it. I was a bit surprised how little time was spent on Amdahl's law/USL (one sentence that you should check it out), but the book spends enough time on non-linearity aspect of scaling just tries to stay away from math. Which is great, given that majority of books in this category become mathy really fast. Overall it's a good intro to the topic.

    This is a very concise and to the point book about application performance. It has captured the essence of performance of applications and capacity planning for an on field engineer. Additionally, Bob Wescott has also provided insightful tips on giving presentation tips especially when telling the bad news. It is a good read and any newbie in performance can take this as a starting point for understanding performance and capacity planning of applications

    Perfect introduction to performance testing. Well written, easy to understand, it is a nice ramp up to the more detail and advance performance books out there.

    A light tome which gives tips for general areas to pay attention to when planning for potential peak workloads. All of it is common sense, but the value of the book lies in laying out easy-to-miss gotchas, such as ensuring your calculation units are the same and your meters are not affecting excessively the thing you are measuring, and the diversity of areas it covers, not just in the technical arena. For instance, planning for the average procurement period for the equipment you need, and calli A light tome which gives tips for general areas to pay attention to when planning for potential peak workloads. All of it is common sense, but the value of the book lies in laying out easy-to-miss gotchas, such as ensuring your calculation units are the same and your meters are not affecting excessively the thing you are measuring, and the diversity of areas it covers, not just in the technical arena. For instance, planning for the average procurement period for the equipment you need, and calling vendors/tech support before crises happen, asking them what information they would need from the system if so-and-so hypothetical issue occurred. The book reads more like a checklist or documentation for things you might forget as you prepare for longer term development. It doesn’t go into detail or specifics, so I can’t say the tips it imparts stick; like a checklist it’s probably good to do a scan of it in the appropriate stage of your development. Otherwise, it’s not a book you finish feeling like you’ve learned something monumental. At least it’s straightforward and reads like consolidated nuggets of wisdom. Pet peeve: I can look past the spelling mistakes (pubic speaking, anyone?), but I can’t look past equations, non-mathematical they might be, typed in regular font. Why would I want to see multiply as an asterisk??

    Estuve tentado a bajarle a 4 estrellas por pequeños detalles. Pero al decir verdad este libro explica muy bien muchos aspectos respecto a performance testing que incluso con la experiencia que tengo, no habia contemplado. En muchos detalles tiene un estilo que me gusta, lleno de ejemplos burdos como una cocina, exposiciones, carros y demas. Creo que este libro es un 'must' para cualquiera que desea incursionar en el mundo de las pruebas de desempeño de IT.

Cambia la perspectiva de solo hacer pruebas de carga, a realmente ver y analizar que es hacer pruebas de desempeño. Muy bueno!

    Found the 3rd chapter on Useful Lawd to be very useful

    An unbelievably compact collection on the tool-agnostic approach to performance analysis! This book should in-fact be read first by anyone stepping into performance testing or performance engineering role. The beauty of this book is simplicity and the way concepts like Little's law are presented, even a statistics newbie can easily munch and digest them. Without much jargon or heavy words, this book simply gives you what you ought to know and care about, when you are in the business of software p An unbelievably compact collection on the tool-agnostic approach to performance analysis!
