Learn measurable C++20 performance engineering through runnable examples, benchmarks, and a VitePress-powered learning site.
This project is a practical guide to common C++ performance topics that are easy to talk about but harder to validate:
- modern CMake and preset-driven builds
- memory and cache layout decisions
- modern C++ performance patterns
- SIMD and vectorization
- concurrency and lock-free basics
- profiling and benchmark-driven reasoning
Every major topic is meant to be readable, buildable, and measurable.
