What are performance budgets?

Performance budgets are predefined limits for metrics like JavaScript bundle size, image weight, or load times that act as constraints during development to prevent performance degradation.

How does it address Core Web Vitals?

It provides specific strategies for improving Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) through better asset management and rendering logic.

When should I use this performance framework?

Use it when experiencing slow load times, preparing for high traffic, or when you need to establish data-driven benchmarks to justify infrastructure changes.

Does this skill help with back-end performance?

Yes, it covers back-end optimization techniques including database indexing, query batching, horizontal scaling, and asynchronous processing.

분석 및 모니터링

Systematically improves application speed and responsiveness using measurement-driven frameworks and performance budgets.

This skill provides a structured methodology for identifying and resolving performance bottlenecks across both front-end and back-end systems. By implementing industry-standard frameworks like RAIL and Core Web Vitals, it helps developers establish performance baselines, set strict budgets, and apply targeted optimizations—such as code splitting, database indexing, and intelligent caching—to ensure applications remain fast, scalable, and user-centric throughout the development lifecycle.
