How a Single Commit Slashed Browser Video Render Frame Time by 80%
A team cut their browser video renderer's frame time from ~0.5-1.0s to ~90-165ms per frame by fixing four issues in one commit. Problems included preview overlays running during export, WebGL context churn, and two other bugs. The fix improved performance without changing output, verified pixel-by-pixel.

This is a solid engineering case study, but the headline's '80%' improvement is relative to an already slow baseline; the real lesson is in the systematic profiling approach.
