Detalles de producto
- An Expert Guide to Software Performance Optimization From mobile and cloud apps to video games to driverless vehicle control, more and more software is time-constrained: It must deliver reliable results seamlessly, consistently, and virtually instantaneously. If it doesn't, customers are unhappy--and sometimes lives are put at risk. When complex software underperforms or fails, software engineers need to identify and address the root causes. This is difficult and, historically, few tools have been available to help. In Understanding Software Dynamics, performance expert Richard L. Sites tackles the problem head on, offering expert methods and advanced tools for understanding complex, time-constrained software dynamics, improving reliability and troubleshooting challenging performance problems. Sites draws on several decades of experience pioneering software performance optimization, as well as extensive experience teaching graduate-level developers. He introduces principles and techniques for use in any environment, from embedded devices to datacenters, illuminating them with examples based on x86 or ARM processors running Linux and linked by Ethernet. He also guides readers through building and applying a powerful, new, extremely low-overhead open-source software tool, KUtrace, to precisely trace executions on every CPU core. Using insights gleaned from this tool, readers can apply nuanced solutions--not merely brute-force techniques such as turning off caches or cores. Measure and address issues associated with CPUs, memory, disk/SSD, networks, and their interactionsFix programs that are always too slow, and those that sometimes lag for no apparent reasonDesign useful observability, logging, and time-stamping capabilities into your codeReason more effectively about performance data to see why reality differs from expectationsIdentify problems such as excess execution, slow instruction execution, waiting for resources, and software locksUnderstanding Software Dynamics will be valuable to experienced software professionals, including application and OS developers, hardware and system architects, real-time system designers, and game developers, as well as advanced students.

Embedded Systems Editorial Review
"Understanding Software Dynamics" by Ian Molyneaux is a highly recommended book for software developers looking for a practical approach to optimization and performance improvement. The book focuses on solving tough issues by stressing the importance of visualizing and seeing the dynamics of software systems instead of relying on averages and other "overalls." It provides useful and practical advice, and respects the time of the reader. The book is recommended for developers with performance-oriented work experience as well as for those who are just starting. The author has summarized a collection of very useful experiences that are not achieved through school but only through a lot of experience. The first part of the book explains the fundamentals and trade-offs, ensuring that the reader revisits all the concepts they learned earlier. The second part of the book covers tools, including not only user space but also kernel level tools. The last chapters of the book provide details on common patterns that programmers deal with every day, even experienced ones. The author educates the reader well with examples and trade-offs. In summary, this is a MUST book for anyone working with systems.
