Code Split Unused JavaScript
Medium Impact+0.5 points estimated
Why It Matters
99KB of unused JavaScript is being loaded unnecessarily, contributing to slower Time to Interactive (4.1s).
How to Fix
Use Next.js dynamic imports with next/dynamic for components not needed on initial render. Analyze your bundle with @next/bundle-analyzer to identify large chunks. Move third-party scripts to Next.js Script component with strategy='lazyOnload' for non-critical functionality.

AI Performance Analysis
This Next.js React site has excellent performance with a score of 98/100, indicating very fast loading times for users. The biggest remaining issue is render-blocking CSS that's delaying your page's initial display by 210 milliseconds, specifically a CSS file that's preventing content from appearing quickly. Additionally, the site is loading about 99 KB of unused JavaScript code that could be removed or deferred to further optimize performance. While these issues exist, they're relatively minor given the already high performance score, but addressing the render-blocking CSS could provide noticeable improvements to your Core Web Vitals.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+1 point estimatedWhy It Matters:
The main CSS file is blocking page render, delaying LCP by 200ms and FCP by 200ms.
How to Fix:
Split your CSS bundle in Next.js by creating critical CSS inline and loading non-critical styles asynchronously. Use next/dynamic with ssr: false for components with heavy CSS. Consider using CSS-in-JS libraries like styled-components to automatically split CSS by component.
Preload Critical Font Resources
High Impact+1 point estimatedWhy It Matters:
The JetBrains Mono font (22KB) is on the critical path with 1.85s load time, potentially causing layout shifts.
How to Fix:
Add a <link rel='preload' as='font'> tag in your Next.js _document.js for jetbrains-mono-600.woff2. Use font-display: swap in your CSS to prevent invisible text during font swap. Consider using next/font for automatic font optimization in Next.js 13+.
