Raj Jain's Book on Computer System Performance Analysis: What You Need to Know and Why



Computer System Performance Analysis: A Review of Raj Jain's Book




Computer system performance analysis is the study of how well a computer system performs under various conditions, such as workload, configuration, hardware, software, etc. It aims to measure, model, simulate, and evaluate the behavior and performance of computer systems, as well as to identify bottlenecks, optimize parameters, compare alternatives, forecast future trends, and plan for capacity. Computer system performance analysis is an essential skill for computer engineers, system administrators, software developers, network managers, and anyone who deals with complex computer systems.

In this article, we will review one of the most comprehensive and influential books on computer system performance analysis: The Art of Computer Systems Performance Analysis by Raj Jain. This book was published in 1991 by John Wiley & Sons, Inc. It covers a wide range of topics, techniques, tools, and applications for performance evaluation. It also provides many examples, case studies, exercises, projects, references, and software tools for readers to learn from. We will summarize the main contents of the book, highlight its contributions and strengths, discuss its limitations and challenges, and provide some suggestions for further reading.


Overview of Raj Jain's Book




The structure and contents of the book




The book consists of seven parts, each containing several chapters. The parts are:



  • Part I: An Overview of Performance Evaluation



  • Part II: Measurement Techniques and Tools



  • Part III: Probability Theory and Statistics



  • Part IV: Experimental Design and Analysis



  • Part V: Simulation



  • Part VI: Queueing Theory



  • Part VII: Stochastic Processes



The book covers both theoretical foundations and practical applications of performance evaluation. It introduces the basic concepts, terminology, principles, methods, metrics, criteria, pitfalls, common mistakes, best practices, professional organizations, journals, conferences, projects, software tools, etc. related to performance evaluation. It also provides detailed explanations, derivations, formulas, tables, figures, graphs, charts, examples, case studies, exercises, projects, references, etc. for each topic. The book is well-organized, well-written, well-illustrated, and well-referenced. It is suitable for both beginners and experts in performance evaluation.


The main contributions and strengths of the book




The book has made many contributions and has many strengths. Some of them are:



  • It is one of the first and most comprehensive books on computer system performance analysis. It covers a wide range of topics, techniques, tools, and applications for performance evaluation. It provides a systematic and unified approach to performance evaluation.



  • It is based on the author's extensive research and teaching experience in performance evaluation. The author is a renowned expert and pioneer in performance evaluation. He has published over 250 papers and 12 books on performance evaluation. He has also taught several courses and workshops on performance evaluation at various universities and companies.



  • It is rich in examples, case studies, exercises, projects, references, and software tools. It provides many real-world examples and case studies from various domains, such as computer systems, networks, databases, operating systems, distributed systems, web servers, graphics, sensors, etc. It also provides many exercises and projects for readers to practice and apply their knowledge and skills. It also provides many references for further reading and research. It also provides many software tools for performance evaluation, such as monitors, load drivers, simulators, analyzers, etc.



  • It is written in a clear, concise, and engaging style. It uses simple language, logical structure, consistent notation, helpful illustrations, informative tables, meaningful graphs, attractive charts, etc. to explain complex concepts and methods. It also uses humor, anecdotes, analogies, metaphors, rhetorical questions, etc. to engage the readers and make the book more interesting and enjoyable.



The limitations and challenges of the book




The book also has some limitations and challenges. Some of them are:



  • It is somewhat outdated. The book was published in 1991 and reflects the state of the art at that time. Since then, many new developments and advances have occurred in performance evaluation. For example, new techniques and tools have been proposed or improved; new applications and domains have emerged or expanded; new standards and benchmarks have been established or updated; new problems and challenges have arisen or intensified; etc. Therefore, some of the contents of the book may be obsolete or incomplete.



  • It is somewhat biased. The book reflects the author's personal opinions and preferences on some topics or issues related to performance evaluation. For example, the author favors certain techniques or tools over others; the author emphasizes certain aspects or perspectives over others; the author criticizes or praises certain works or authors over others; etc. Therefore, some of the contents of the book may be subjective or controversial.



  • It is somewhat difficult. The book covers many topics that require mathematical background and analytical skills. For example, the book uses probability theory and statistics extensively; the book derives many formulas and equations rigorously; the book presents many models and algorithms formally; etc. Therefore, some of the contents of the book may be challenging or intimidating for some readers.



Measurement Techniques and Tools




Types of workloads and benchmarks




A workload is a set of requests made by the users of a system. A benchmark is a standard workload that can be used to compare the performance of different systems or components. The book introduces various types of workloads and benchmarks for performance evaluation.


Some of the types of workloads are:



  • Addition instruction: A simple workload that consists of executing a single instruction repeatedly.



  • Instruction mixes: A workload that consists of executing a sequence of instructions with different frequencies.



  • Kernels: A workload that consists of executing a small piece of code that represents a typical operation or function.



  • Synthetic programs: A workload that consists of executing a program that mimics the behavior or characteristics of a real application.



  • Application benchmarks: A workload that consists of executing a real application or a subset of it.



Some of the popular benchmarks are:



  • SPEC: A set of benchmarks for measuring the performance of CPU-intensive applications.



  • TPC: A set of benchmarks for measuring the performance of transaction-processing systems.



  • Dhrystone: A benchmark for measuring the performance of integer arithmetic operations.



  • Whetstone: A benchmark for measuring the performance of floating-point arithmetic operations.



LINPACK: A benchmark for measuring the performance of linear algebra operations. 71b2f0854b
