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.

About the Author
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).

Best book about system performance ever
By Olivier Bernhard
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.

Technical book of the year
By Forrest L. Norvell
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.

This book has a fixed spot on my desk!
By Pietro Michiardi
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.
