How can I improve GitHub Actions performance without guessing?

Question

A performance change should improve the measured workload without sacrificing correctness or wasting capacity. Which measurements and bottlenecks should be considered first?

Measure build and test time by step, then cache expensive reproducible dependencies and parallelize independent work. Use concurrency groups to avoid redundant deployments. Excessive job fan-out can increase startup overhead and cost without improving the overall critical path.
