There are several ways to improve the speed of GitHub Actions workflows : Use caching — Cache dependencies like npm packages or build artifacts to avoid reinstalling every run. Run jobs in parallel — Split tests or tasks into multiple jobs so they run at the same time. Use smaller runners — Optimize the environment and avoid unnecessary services. |

Use smaller runners — Optimize the environment and avoid unnecessary services.
Limit triggers — Run workflows only on needed branches or paths to reduce unnecessary runs.
Reuse workflows — Create reusable workflows to keep configs clean and efficient.
Even small optimizations like caching dependencies can significantly reduce workflow time.
