Optimize Critical Resource Chain
High Impact+10 points estimated
Why It Matters
JavaScript dependency chain takes 1.3 seconds to complete, directly impacting both FCP (3.2s) and LCP (3.5s).
How to Fix
Preload the critical JavaScript files using <link rel='preload' as='script'> for index-B4LjLqjp.js and index-DqPXE7gF.js. Inline critical JavaScript directly in HTML to eliminate the network requests. Consider bundling these two dependent scripts into a single file to reduce the chain length.

AI Performance Analysis
This website has good performance with a score of 84/100, but there's significant room for improvement in loading speed. The biggest issue is that your First Contentful Paint takes 3.2 seconds and Largest Contentful Paint takes 3.5 seconds, both of which are too slow for optimal user experience. The main culprits are unused JavaScript code (wasting 104 KB, particularly from Google Analytics and React components) and an unoptimized background image that could save 24 KB with better compression. Removing unused JavaScript and optimizing your images could easily push your performance score above 90 and make your site feel much faster to visitors.
Other Optimization Recommendations
Eliminate Unused JavaScript Code
High Impact+8 points estimatedWhy It Matters:
104 KiB of unused JavaScript is delaying LCP by 150ms and blocking the main thread unnecessarily.
How to Fix:
Remove or defer the Google Analytics script (66KB unused) by loading it after page load using gtag('config') with async. Split the React bundle and lazy load non-critical components. Use webpack-bundle-analyzer to identify and tree-shake unused code from the 40KB unused React bundle.
Compress Backdrop Video Poster
Medium Impact+3 points estimatedWhy It Matters:
The backdrop video poster image can save 24KB (55% reduction) and improve LCP by 150ms.
How to Fix:
Increase compression on the backdrop-home.webp file using tools like Squoosh or ImageOptim. Reduce quality to 75-80% which typically saves 20-30% file size with minimal visual impact. Consider using responsive images with srcset for different screen sizes to serve smaller images on mobile devices.
