Every Computer Performance Book


Book Description

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.




Performance by Design


Book Description

Practical, real-world solutions are given to potential problems covering the entire system life cycle. This book describes how to map real-life systems (databases, data centers, and e-commerce applications) into analytic performance models. The authors elaborate upon these models and use them to help the reader better understand performance issues.

Art of Computer Systems Performance Analysis


Book Description

The seminal guide to performance analysis, with new information and essential advice The Art of Computer Systems Performance Analysis is the essential guide to practical performance analysis tools and techniques. This easy to follow guide presents a unique blend of measurement, simulation, and modeling methods in a straightforward, problem-oriented fashion, and integrates essential queuing theory with data analysis, experimental design, and the most powerful tools in performance analysis. This updated edition includes new chapters on Time Series Analysis and Long-Range Dependence, over 150 updated examples and cases studies, and a host of special tricks that demonstrate system superiority. Instructor's Materials, including PowerPoint slides, syllabus, and solutions for expanded exercises beyond the end-of-chapter exercises, is available making it ideal for classroom use. Performance testing measures a system's responsiveness and stability under a particular workload, and can serve to investigate, measure, validate, or verify other quality attributes of the system, including scalability, reliability, and resource usage. This book is the seminal work on the topic, providing expert guidance to systems professionals for over twenty-two years. Comprehensive coverage of all aspects of performance measurement makes it a valuable resource for students and professionals alike. Understand technique and metric criteria, and avoid common mistakes Collect, analyze, and present measurement data with the most powerful techniques Provide the maximum amount of information with the minimum number of experiments Determine the number of sizes of components required (capacity planning) Evaluate design alternatives, correctly compare two or more systems, and determine the optimal value of a parameter (system tuning) Analysis in technology using statistics and other methodologies has become one of the most important, in-demand skills in the corporate and enterprise world. While practitioners may create new systems, they are often asked to modify, expand, or document existing systems – many of which have been grown haphazardly. Art of Computer Systems Performance Analysis provides the information, skills, and tools analysts need to tackle any system with confidence.




Analyzing Computer System Performance with Perl::PDQ


Book Description

To solve performance problems in modern computing infrastructures, often comprising thousands of servers running hundreds of applications, spanning multiple tiers, you need tools that go beyond mere reporting. You need tools that enable performance analysis of application workflow across the entire enterprise. That's what PDQ (Pretty Damn Quick) provides. PDQ is an open-source performance analyzer based on the paradigm of queues. Queues are ubiquitous in every computing environment as buffers, and since any application architecture can be represented as a circuit of queueing delays, PDQ is a natural fit for analyzing system performance. Building on the success of the first edition, this considerably expanded second edition now comprises four parts. Part I contains the foundational concepts, as well as a new first chapter that explains the central role of queues in successful performance analysis. Part II provides the basics of queueing theory in a highly intelligible style for the non-mathematician; little more than high-school algebra being required. Part III presents many practical examples of how PDQ can be applied. The PDQ manual has been relegated to an appendix in Part IV, along with solutions to the exercises contained in each chapter. Throughout, the Perl code listings have been newly formatted to improve readability. The PDQ code and updates to the PDQ manual are available from the author's web site at www.perfdynamics.com
