In the modern era of computing, performance has become a "killer feature." While hardware continues to evolve with increasingly complex microarchitectures, modern software often remains massively inefficient. This systemic inefficiency not only cuts into corporate margins and slows down user experiences but also contributes to significant energy waste and global carbon emissions. "Performance Analysis and Tuning on Modern CPUs" by renowned performance expert Denis Bakhvalov addresses these critical challenges by providing a comprehensive, hands-on guide to low-level software optimization. The book is specifically designed for software professionals who want to understand how their code interacts with the underlying hardware and how to squeeze every bit of performance out of modern processors. This second edition has been significantly expanded, nearly doubling in size compared to the original release, and includes new in-depth case studies, hands-on exercises, and updated content reflecting the latest advancements in CPU technology. Readers will embark on a detailed journey starting with the fundamentals of performance measurement, learning how to account for noise in modern systems and how to set up robust benchmarking environments for production and development. The book delves deep into the intricacies of CPU microarchitecture, explaining concepts such as pipelining, out-of-order execution, speculation, and the memory hierarchy in a way that is both accessible and technically rigorous. Central to the text are the chapters on performance analysis approaches and advanced tools. Bakhvalov provides expert guidance on using industry-standard tools like Intel VTune Profiler and the Linux 'perf' utility. He introduces the Top-down Microarchitecture Analysis Method (TMAM), a powerful framework for identifying whether a program is bottlenecked by instruction fetching, execution resources, or memory latency. The latter half of the book focuses on practical tuning techniques. It covers optimizing memory accesses through better cache utilization, improving computation efficiency with SIMD, enhancing branch prediction, and refining machine code layout for better instruction cache performance. Whether you are an application developer, a systems programmer, or a student, this book provides the necessary tools to transform inefficient code into high-performance software.
