Build Performance Baseline & Optimization Overview Before optimizing a build, you need a baseline . Without measurements, optimization is guesswork. This skill covers how to establish baselines and apply systematic optimization techniques. Related skills: - — binlog-based bottleneck identification - — Inputs/Outputs and up-to-date checks - — parallel and graph build tuning - — glob and import chain optimization --- Step 1: Establish a Performance Baseline Measure three scenarios to understand where time is spent: Cold Build (First Build) No previous build output exists. Measures the full end-…
