Book Description
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(R) and Unix(R) 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(R), Fedora(R), CentOS, and the illumos-based Joyent(R) SmartOS(TM) and OmniTI OmniOS(R). 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.

Pages : 302

Book Description
The secret of achieving and sustaining organizational excellence revealed In an ever-changing world where only a third of excellent organizations stay that way over the long term, and where even fewer are able to implement successful change programs, leaders are in need of big ideas and new tools to thrive. In Beyond Performance, McKinsey & Company's Scott Keller and Colin Price give you everything you need to build an organization that can execute in the short run and has the vitality to prosper over the long term. Drawing on the most exhaustive research effort of its kind on organizational effectiveness and change management, Keller and Price put hard science behind their big idea: that the health of an organization is equally as important as its performance. In the book's foreword, management guru Gary Hamel refers to this notion as "a new manifesto for thinking about organizations." The authors illustrate why copying management best practices from other companies is more dangerous than helpful Clearly explains how to determine the mutually reinforcing combination of management practices that best fits your organization's context Provides practical tools to achieve superior levels of performance and health through a staged change process: aspire, assess, architect, act, and advance. Among these are new techniques for dealing with those aspects of human behavior that are seemingly irrational (and therefore confound even the smartest leaders), yet entirely predictable Ultimately, building a healthy organization is an intangible asset that competitors copy at their peril and that enables you to skillfully adapt to and shape your environment faster than others—giving you the ultimate competitive advantage.

Book Description
THESE HABITS WILL MAKE YOU EXTRAORDINARY. Twenty years ago, author Brendon Burchard became obsessed with answering three questions: 1. Why do some individuals and teams succeed more quickly than others and sustain that success over the long term? 2. Of those who pull it off, why are some miserable and others consistently happy on their journey? 3. What motivates people to reach for higher levels of success in the first place, and what practices help them improve the most After extensive original research and a decade as the world’s leading high performance coach, Burchard found the answers. It turns out that just six deliberate habits give you the edge. Anyone can practice these habits and, when they do, extraordinary things happen in their lives, relationships, and careers. Which habits can help you achieve long-term success and vibrant well-being no matter your age, career, strengths, or personality? To become a high performer, you must seek clarity, generate energy, raise necessity, increase productivity, develop influence, and demonstrate courage. The art and science of how to do all this is what this book is about. Whether you want to get more done, lead others better, develop skill faster, or dramatically increase your sense of joy and confidence, the habits in this book will help you achieve it faster. Each of the six habits is illustrated by powerful vignettes, cutting-edge science, thought-provoking exercises, and real-world daily practices you can implement right now. If you’ve ever wanted a science-backed, heart-centered plan to living a better quality of life, it’s in your hands. Best of all, you can measure your progress. A link to a free professional assessment is included in the book.
