Description
From mobile and cloud apps to video games to driverless vehicle control, more and more software is time-constrained: it must reliably deliver results seamlessly, consistently, and virtually instantaneously. If it fails to do so, customers are unhappy -- and sometimes lives are put at risk. When time-constrained software does not meet its requirements, software engineers must quickly identify and address the root causes. This is difficult, and few tools have been available to help.Now, world-renowned software performance expert Richard Sites tackles the problem head on, offering expert methods and advanced tools for understanding complex time-constrained software dynamics, improving software reliability, and troubleshooting challenging performance problems. He addresses CPU, memory, disk, network, and more, helping you fix programs that are always too slow, or work well at times but inexplicably slow down at other times.Sites draws on several decades of experience pioneering software performance optimization, and extensive experience teaching developers at the graduate level. He introduces principles and techniques you can 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. Sites also guides readers through building and applying a powerful new extremely-low-overhead open source software tool, KUtrace, to trace exactly what is executing on every CPU core. Using insights gleaned from this tool, readers can apply nuanced approaches to performance enhancement -- not merely brute-force techniques such as turning off caches or cores.
