Reduce JavaScript Bundle Size
High Impact+12 points estimated
Why It Matters
JavaScript execution blocks the main thread for 1.4s and 378KB of unused JS code slows initial load.
How to Fix
Enable Next.js tree shaking by using named imports instead of default imports. Split large chunks using dynamic imports for non-critical components. Remove unused dependencies and implement code splitting for route-based bundles.

AI Performance Analysis
This Next.js site has good performance with a score of 90/100, but suffers from excessive JavaScript processing that's significantly slowing down interactivity. The biggest issue is that JavaScript takes 15.5 seconds to become fully interactive, with heavy script evaluation and compilation blocking the main thread for over 2 seconds. The site is also loading an oversized 1.5MB image that could be compressed by 1.4MB using modern formats like WebP and proper responsive sizing. Reducing JavaScript bundle sizes, removing unused code (378KB worth), and optimizing that large banner image would dramatically improve the user experience and push this site into excellent performance territory.
Other Optimization Recommendations
Optimize Large Banner Image
High Impact+8 points estimatedWhy It Matters:
The Sub_banner_Icon.png is 1.5MB and wastes 1,497 KiB through poor compression and oversizing.
How to Fix:
Convert the banner image to WebP format to save ~400KB. Resize from 2908x2359 to proper display dimensions (630x511) to save ~1.4MB. Use Next.js Image component with responsive sizes for automatic optimization.
Eliminate Render Blocking CSS
Medium Impact+5 points estimatedWhy It Matters:
The CSS file blocks First Contentful Paint by 150ms, delaying critical rendering path.
How to Fix:
Inline critical CSS directly in the HTML head using Next.js styled-jsx or CSS-in-JS. Move non-critical styles to load after page interactive. Use Next.js font optimization to prevent layout shifts from web fonts.
