Optimization: a broad intro
summary
High-level roadmap to find and fix real bottlenecks: use profilers like Unity profiler and Intel VTune plus GPU tools (RenderDoc, PIX) to measure actual function times and memory use, not guess. Treat optimization as diagnosis: profile, change, reprofile. Favor removing work over microtuning — “the fastest code is code that doesn’t run” — and prefer contiguous data structures and small call depth. Do back-of-the-envelope hardware math (example: target hardware can handle one million particles per frame) to decide if a problem is memory- or compute-bound.
