About This Site | Tuning - Wyatt's Notes

Wyatt’s Notes offers comprehensive study materials for performance tuning and optimisation. These notes cover profiling, benchmarking, memory management, CPU optimisation, and I/O tuning, building the skills needed to extract maximum performance from software and systems.

These notes are created by Wyatt, an educator and content developer with expertise in systems performance engineering. Content follows a structured progression from measurement methodology through specific optimisation techniques to production performance management.

Materials emphasise the measure-before-optimise philosophy and the systematic approach that professional performance engineers use. Every concept includes practical examples and explains the underlying hardware and OS mechanisms that determine performance.

• Measurement covering profiling tools, benchmarks, and metrics
• CPU optimisation with cache effects, branch prediction, and SIMD
• Memory management covering allocation patterns and garbage collection
• I/O tuning with disk, network, and file system optimisation
• Database performance covering query optimisation and indexing strategies

Wyatt develops resources across systems, databases, and programming, providing the full-stack perspective that enhances performance tuning materials. Content is informed by performance engineering literature, tool documentation, and production optimisation experience.

• Linux — Linux administration resources
• Databases — Database design and SQL notes
• C++ — C++ programming resources

Start with measurement methodology to build the foundation for effective tuning. Each topic progresses from theory to practical optimisation. Use the practice exercises to develop your performance engineering skills.

This site provides comprehensive study materials covering:

• Performance tuning
• Profiling
• Optimisation

Each topic includes detailed explanations, worked examples, and practice problems designed to build deep understanding.

1. Start with fundamentals — begin with the core topics before moving to advanced material
2. Work through examples — every concept includes worked examples with step-by-step solutions
3. Test yourself — use the practice problems and diagnostic tests to identify knowledge gaps
4. Cross-reference — related topics on other sites in the Wyatt’s Notes network provide additional perspectives

• Flashcards — spaced repetition flashcards for key concepts and formulas
• Practice Problems — graded problems from basic to advanced
• Diagnostic Tests — identify your strengths and weaknesses
• Worked Examples — step-by-step solutions to common problems

These notes are informed by standard university textbooks including systems programming texts. While the notes follow the general structure of these texts, they are not a substitute for reading the primary sources.
