Book excerpt: 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.

Download or read book Beyond Performance written by Scott Keller and published by John Wiley & Sons. This book was released on 2011-06-01 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: "Performance" has multiple and often overlapping meanings that signify a wide variety of social behaviors. In this invitation to reflect on the power of performance, Diana Taylor explores many of its uses and iterations: artistic, economic, sexual, political, and technological performance; the performance of everyday life; and the gendered, sexed, and racialized performance of bodies.
