Textbook in PDF format Modern software is often far less efficient than it could be. Many applications run on modern CPUs with poorly optimized code, leading to unnecessary power consumption and increased environmental impact. Inefficient programs also reduce companies’ profitability and can negatively affect their market value. For a long time, performance engineering was considered a niche discipline practiced mainly by enthusiasts. Today, however, it is becoming increasingly important as organizations recognize how inefficient software directly affects costs and business performance. In many cases, performance has become a decisive competitive advantage. In Performance Analysis and Tuning on Modern CPUs, performance specialist Denis Bakhvalov explains how to apply advanced techniques and tools to perform low-level optimizations. By studying this book, readers will learn how to identify the root causes of performance regressions and uncover opportunities to improve application efficiency. The second edition expands on the original material with detailed case studies and practical exercises designed to reinforce the concepts. This book is aimed at experienced developers, including those working on applications, libraries, compilers, and operating systems, as well as advanced students in computer science. The knowledge and techniques presented can be applied directly in professional development work and can help accelerate career growth
