Why It Matters

AI Performance Analysis

This website has excellent performance with a score of 94/100, but there are still some optimization opportunities that could make it even faster. The biggest issue is inefficient caching policies on images and resources, which could save 693 KiB and improve loading times by 600ms for repeat visitors. The site is also loading 99 KiB of unused JavaScript code, with nearly half of the main script file going unused, which adds unnecessary 460ms to load times. Additionally, the CSS file has 84% unused rules, wasting 18 KiB of bandwidth. Fixing these caching policies and removing unused code could push this already strong-performing site closer to a perfect score while significantly improving the experience for returning visitors.

Other Optimization Recommendations

Implement Longer Cache Lifetimes

High Impact+8 points estimated

Why It Matters:

Current 1-hour cache lifetime wastes 693 KiB on repeat visits and delays LCP by 600ms.

How to Fix:

Configure your CDN (Hostinger) to cache images for 1 year (31536000 seconds) instead of 1 hour. Update Supabase storage bucket policy to set Cache-Control: max-age=31536000 for static images. Add versioning to image URLs for cache busting when needed.

Remove Unused JavaScript Code

High Impact+6 points estimated

Why It Matters:

48% of your main JavaScript bundle (99 KiB) is unused, adding 460ms to load time.

How to Fix:

Analyze your main bundle with webpack-bundle-analyzer to identify unused code. Implement code splitting to separate components into smaller chunks that load on demand. Use dynamic imports for non-critical sections like modals and secondary features.
