• Use when optimizing for Core Web Vitals (LCP, FID, CLS)
• Use when reducing JavaScript bundle size
• Use when improving Time to Interactive (TTI)
• Use when optimizing images and assets
• Use when implementing caching strategies
• Use when debugging performance bottlenecks
• Use when preparing for performance audits
