Performance optimization secrets
Speed up your website and improve user experience with these proven optimization techniques that deliver real results.
Image Optimization
Use modern formats like WebP, implement lazy loading, and serve responsive images. Images often account for 50%+ of page weight.
Pro Tip: Compress images to 85% quality - the sweet spot between file size and visual quality.
Code Splitting
Break your JavaScript into smaller chunks and load only what is needed. This dramatically reduces initial load time.
Pro Tip: Use dynamic imports for routes and heavy components to reduce bundle size by 40-60%.
Caching Strategy
Implement multi-layer caching: browser cache, CDN, and server-side caching. Serve static content from edge locations.
Pro Tip: Set proper cache headers and use service workers for offline-first experiences.
Critical Rendering Path
Optimize the critical rendering path by inlining critical CSS, deferring non-critical resources, and minimizing render-blocking resources.
Pro Tip: Aim for First Contentful Paint under 1.8s and Time to Interactive under 3.8s.
