Keeping Performance Budgets on Track
Establish budgets for bundle size and response times, then enforce them automatically.
Performance budgets make speed a measurable requirement instead of a vague goal.
### How to implement
1. Decide the metrics that matter for your product (LCP, TTFB, bundle size).
2. Track them in CI using Lighthouse CI or custom scripts.
3. Block merges or deployments when a regression exceeds the agreed threshold.
When developers see speed as part of the definition of done, users feel the difference.
