Implement Browser Cache Headers
High Impact+12 points estimated
Why It Matters
Missing cache headers force 900 KiB of assets to reload on every visit, delaying LCP by 4 seconds.
How to Fix
Configure your web server to set Cache-Control headers for static assets. Set long cache times (1 year) for versioned files like main-CWn_4G37.js. Use ETags for validation caching. Implement cache-busting with file hashing for updates.

AI Performance Analysis
This website has poor performance with a score of 71/100, primarily due to slow loading times that hurt user experience. The biggest problem is excessive unused JavaScript code (223 KiB that could be removed), which is delaying both First Contentful Paint and Largest Contentful Paint by 1.2 seconds each. Additionally, render-blocking CSS files are preventing the page from displaying content quickly, and the site has no browser caching configured, forcing users to re-download all assets on every visit. Removing unused JavaScript, implementing proper caching headers, and deferring non-critical CSS could improve the performance score by 15-25 points and significantly reduce the current 4.4-second load time.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+15 points estimatedWhy It Matters:
228 KiB of unused JavaScript delays LCP and FCP by 1.2 seconds each.
How to Fix:
Analyze your main bundle using webpack-bundle-analyzer to identify unused code. Split your JavaScript into smaller chunks using dynamic imports for features not needed on initial load. Remove or defer unused libraries like motion animations until user interaction. Tree-shake dependencies to eliminate dead code.
Eliminate Render Blocking CSS
Medium Impact+8 points estimatedWhy It Matters:
CSS file blocks initial page rendering and delays First Contentful Paint by 600ms.
How to Fix:
Inline critical above-the-fold CSS directly in the HTML head. Load non-critical CSS asynchronously using media='print' onload trick or loadCSS library. Split CSS into critical and non-critical bundles using tools like Critical or PurgeCSS.
