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.

Step 1: Establish a Performance Baseline

Measure three scenarios to understand where time is spent:
