The Complete Guide to Optimizing Systems Performance


Written by the winner of the 2013 LISA Award for Outstanding Achievement in System Administration

Large-scale enterprise, cloud, and virtualized computing systems have introduced serious performance challenges. Now, internationally renowned performance expert Brendan Gregg has brought together proven methodologies, tools, and metrics for analyzing and tuning even the most complex environments. Systems Performance: Enterprise and the Cloud focuses on Linux® and Unix® performance, while illuminating performance issues that are relevant to all operating systems. You’ll gain deep insight into how systems work and perform, and learn methodologies for analyzing and improving system and application performance. Gregg presents examples from bare-metal systems and virtualized cloud tenants running Linux-based Ubuntu®, Fedora®, CentOS, and the illumos-based Joyent® SmartOS™ and OmniTI OmniOS®. He systematically covers modern systems performance, including the “traditional” analysis of CPUs, memory, disks, and networks, and new areas including cloud computing and dynamic tracing. This book also helps you identify and fix the “unknown unknowns” of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish.


Coverage includes

• Modern performance analysis and tuning: terminology, concepts, models, methods, and techniques

• Dynamic tracing techniques and tools, including examples of DTrace, SystemTap, and perf

• Kernel internals: uncovering what the OS is doing

• Using system observability tools, interfaces, and frameworks

• Understanding and monitoring application performance

• Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling

• Memory optimization: virtual memory, paging, swapping, memory architectures, busses, address spaces, and allocators

• File system I/O, including caching

• Storage devices/controllers, disk I/O workloads, RAID, and kernel I/O

• Network-related performance issues: protocols, sockets, interfaces, and physical connections

• Performance implications of OS and hardware-based virtualization, and new issues encountered with cloud computing

• Benchmarking: getting accurate results and avoiding common mistakes


This guide is indispensable for anyone who operates enterprise or cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others new to optimization, it also provides exercises reflecting Gregg’s extensive instructional experience.


Biographie de l'auteur

Brendan Gregg, lead performance engineer at Joyent, analyzes performance and scalability throughout the software stack. As performance lead and kernel engineer at Sun Microsystems (and later Oracle), his work included developing the ZFS L2ARC, a pioneering file system technology for improving performance using flash memory. He has invented and developed many performance tools, including some that ship with Mac OS X and Oracle® Solaris™ 11. His recent work has included performance visualizations for Linux and illumos kernel analysis. For contributions to system administration, and his work on performance analysis methodologies, he is the recipient of the USENIX 2013 LISA Award for Outstanding Achievement in System Administration. He is also a coauthor of Dtrace: Dynamic Tracing in Oracle Solaris, Mac OS X and FreeBSD (Prentice Hall, 2011),  and Solaris™ Performance and Tools: DTrace and MDB Techniques for Solaris 10 and OpenSolaris, (Prentice Hall, 2007).

HASH(0x9b117750) étoiles sur 5 Best book about system performance ever 25 octobre 2013
Par Olivier Bernhard - Publié sur
Format: Format Kindle Achat vérifié
I can still remember when i was downloading Brendan Gregg webinars about disk I/Os. It was obvious, this guy knew a lot about it and could explain it in most efficient way. I was just getting frustrated that all this knowledge was not put into a book. A few years later the "precious" is here ! This book is simply amazing, covering all possible aspects of system performance. You will not be overwhelmed : Brendan knows how to find a good balance between over simplification and too much details. You will learn what you really need to know (the internals), the good methods, the right tools. I can't thank enough Brendan Gregg to bring this new master piece i was waiting for so long.

If you're a system administration, a developper, a "true" database administrator trying to understand how your database is likely to interact with the operating system & hardware, here you are. You can't afford to miss this book.

HASH(0x9b11799c) étoiles sur 5 This book has a fixed spot on my desk! 16 décembre 2013
Par Pietro Michiardi - Publié sur
Format: Broché
I enjoyed reading this book because of its technical depth and rigour: topics are very well developed, and references are generally appropriate (although I sometimes found myself hoping for some must-read "academic" papers to be referenced as well).

In my humble opinion, the use of this book goes beyond that of being a reference for system administrators and performance engineers: I use it extensively to guide my experimental evaluation of the performance of new applications or system components, as it provides solid methodologies that can be clearly described and used by others to validate results.

To conclude, I highly recommend this book: it should become mandatory reading material for students working in systems research.

HASH(0x9b117d80) étoiles sur 5 Technical book of the year 3 décembre 2013

Good books on analyzing performance seem to come out once every ten years or so, and this is this generation's classic work. Brendan's background in the development of DTrace and the analytic framework that he and his colleagues at Sun / Oracle and then Joyent have built up around it, as well as the methodologies he's been instrumental in developing (most notably the USE method), give him pretty much a unique level of analytic power. He organizes this material conceptually, grounding it in a discussion of tools and methods in chapter 2 and then working through those methods in the chapters that examine such performance topics as CPUs, operating systems, applications, and the like.

HASH(0x9b117c48) étoiles sur 5 Excellent book, I've learned a lot from it 13 juillet 2014
Par Joe in Los Angeles - Publié sur
Format: Format Kindle Achat vérifié
I found this to be an excellent resource. I've been reading it slowly in my spare time and on plane rides and it's a big book, I'm about half way now.

The book is well written and I enjoy the breadth and depth of the topics. Each of which is covert from a near beginner to an almost expert level. Which is good for me because my understanding of the topics Brendan covers spans the same range, some I've barely heard of others I use almost every week.

He does cover both Linux and Solaris which make some of the procedure descriptions a bit repetititve but we do have a 90-10 split of Linux and Solaris machines and I may get stuck on a Solaris box one of these days.

My only criticism so far is the glossary could be more complete, I would like to have had EVERY acronym he uses in there because of the slow pace, I'm reading I don't remember the ones we don't use. Very common problem.

I'm using it to increase my skills in tracking down performance problems in software I develop and deploy for an international scientific collaboration. Fortunately for me, I haven't had a hard performance problem since I started reading the book, but I'm not sure how quickly I could use such a tome to solve a specific problem. On the other hand I have used many things I've learned to gain a better understanding of things that are working.

I like most of the reviewers so far would recommend it for anyone with even basic skills who is interested in understanding the issues affecting System Performance.

I gave it 4 stars instead of 5 because of how broad an audience it addresses. While that's a good thing in that people can find what they need it also means there is a lot they don't need. Nobody would write a book like this that only had what I need on the topic but I'm saving the 5 star rating for something that knocks my socks off. This is well worth the price if you take the time to not only read it but become familiar with the techniques presented.

HASH(0x9b117b64) étoiles sur 5 An outstanding and essential UNIX/Linux performance text! 6 novembre 2013
Par Harry J. Foxwell, PhD - Publié sur
Format: Broché Achat vérifié
Long ago, the prerequisite UNIX performance book was Adrian Cockcroft's 1994 classic, Sun Performance and Tuning: Sparc & Solaris, later updated in 1998 as Java and the Internet. As Solaris evolved to include the invaluable DTrace observability features, new essential performance references have been published, such as Solaris Performance and Tools: DTrace and MDB Techniques for Solaris 10 and OpenSolaris (2006) by McDougal, Mauro, and Gregg, and DTrace: Dynamic Tracing in Oracle Solaris, Mac OS X and FreeBSD (2011), also by Mauro and Gregg.

Much has occurred in Solaris Land since those books appeared, notably Oracle's acquisition of Sun Microsystems in 2010 and the demise of the OpenSolaris community. But operating system technologies have continued to improve markedly in recent years, driven by stunning advances in multicore processor architecture, virtualization, and the massive scalability requirements of cloud computing.

A new performance reference was needed, and I eagerly waited for something that thoroughly covered modern, distributed computing performance issues from the ground up. Well, there's a new classic now, authored yet again by Brendan Gregg, former Solaris kernel engineer at Sun and now Lead Performance Engineer at Joyent.

Systems Performance: Enterprise and the Cloud is a modern, very comprehensive guide to general system performance principles and practices, as well as a highly detailed reference for specific UNIX and Linux observability tools used to examine and diagnose operating system behaviour. It provides thorough definitions of terms, explains performance diagnostic Best Practices and "Worst Practices" (called "anti-methods"), and covers key observability tools including DTrace, SystemTap, and all the traditional UNIX utilities like vmstat, ps, iostat, and many others.

The book focuses on operating system performance principles and expands on these with respect to Linux (Ubuntu, Fedora, and CentOS are cited), and to Solaris and its derivatives [1]; it is not directed at any one OS so it is extremely useful as a broad performance reference.

The author goes beyond the intricacies of performance analysis and shows how to interpret and visualize statistical information gathered from the observability tools. It's often difficult to extract understanding from voluminous rows of text output, and techniques are provided to assist with summarizing, visualizing, and interpreting the performance data.

Gregg includes myriad useful references from the system performance literature, including a "Who's Who" of contributors to this great body of diagnostic tools and methods.

This outstanding book should be required reading for UNIX and Linux system administrators as well as anyone charged with diagnosing OS performance issues. Moreover, the book can easily serve as a textbook for a graduate level course in operating systems [2].

[1] Solaris 11, of course, and Joyent's SmartOS (developed from OpenSolaris)

[2] Gregg has taught system performance seminars for many years; I have also taught such courses...this book would be perfect for the OS component of an advanced CS curriculum.
