Deepen your knowledge of system performance with the book Systems Performance by Brendan Gregg - an expert publication focused on analyzing and tuning the performance of computer systems.

The book Systems Performance covers the principles of measurement, diagnosis, and finding performance bottlenecks. In environments where performance and stability are often handled under time pressure, it offers a structured overview of procedures, concepts, and methods that can help better understand the behavior of systems and applications. It is not software or an automatic “optimization tool” - results depend on the specific environment, correct measurement, and chosen approach.

The publication can be useful for infrastructure administrators and developers, as well as technically minded readers who want to better understand why systems slow down, how to collect relevant metrics, and how to proceed when troubleshooting performance issues. Instead of promising instant speedups, it primarily provides know-how and a framework for systematic performance work.

Main benefits of the book Systems Performance

• A methodical approach to performance analysis and finding causes of slowdowns.
• Understanding resource utilization (CPU, memory, disk, network) and their impact on system behavior.
• Diagnostics and measurement - emphasis on metrics, profiling, and interpretation of results.
• Practical applicability - for readers engaged with performance professionally or academically.
• A comprehensive context for working with performance across system layers.

General features of the publication
