AI Performance Analysis
This Next.js site has poor performance with a score of 55/100, indicating significant user experience issues. The biggest problem is multiple page redirects that are adding nearly 37 seconds of delay, catastrophically slowing down both First Contentful Paint and Largest Contentful Paint metrics. Additionally, the site is loading oversized, unoptimized images (saving potential of 1MB) and serving 1.5MB of unused JavaScript code that's not needed for the current page. Fixing the redirect chain and optimizing images would provide the most dramatic performance improvements, potentially boosting the score by 30+ points.
Other Optimization Recommendations

High Impact+35 points estimatedWhy It Matters:
Redirect chains delay page load by 36.8 seconds, severely impacting LCP and user experience.
How to Fix:
Configure your Next.js application to serve the login page directly without authentication redirects. Implement client-side authentication checks after initial page load. Update server configurations to avoid the OAuth redirect chain for anonymous users.
Reduce Unused JavaScript Bundle
High Impact+20 points estimatedWhy It Matters:
1.5MB of unused JavaScript delays LCP by 13.8 seconds and blocks page interactivity.
How to Fix:
Enable Next.js tree shaking by using ES6 imports and avoiding default imports for libraries. Implement dynamic imports for non-critical components using next/dynamic. Split your main bundle by moving authentication logic to separate chunks that load conditionally.
