The Complete Guide to Optimizing Systems Performance Written by the winner of the2013 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.
Traffic & Performance
Techniques that ensure traffic performance in telecommunication systems and a methodology that can be applied to all phases of development are presented in this introduction to telecommunication networks....
Mechatronic systems are used in a range of consumer products from large-scale braking systems in vehicular agents to small-scale integrated sensors in mobile phones. To keep pace in the competitive consumer electronics industry, companies need to continuously improve servo evaluation and position control of these mechatronic systems. Advances in High-Performance Motion Control of Mechatronic Systems covers advanced control topics for mechatronic applications. In particular, the book examines control systems design for ultra-fast and ultra-precise positioning of mechanical actuators in mechatronic systems. The book systematically describes motion control design methods for trajectory design, sampled-data precise positioning, transient control using sw...
High-Performance Systems and Programming
Focusing on the line of high-performance microcontrollers offered by Microchip, Microcontrollers: High-Performance Systems and Programming discusses the practical factors that make the high-performance PIC series a better choice than their mid-range predecessors for most systems. However, one consideration in favor of the mid-range devices is the abundance of published application circuits and code samples. This book fills that gap. Possibility of programming high-performance microcontrollers in a high-level language (C language) Source code compatibility with PIC16 microcontrollers, which facilitates code migration from mid-range to PIC18 devices Pin compatibility of some PIC18 devices with their PIC16 predecessors, making the reuse of PIC16 contr...
