Reduce Unused JavaScript Bundle Size

High Impact+20 points estimated

Why It Matters

756 KiB of unused JavaScript delays LCP by 3.9 seconds and wastes 3.9 seconds of load time.

How to Fix

Implement code splitting in your Next.js app using dynamic imports for non-critical components. Use Next.js bundle analyzer (@next/bundle-analyzer) to identify large chunks. Remove polyfills for modern baseline features (Array.at, Object.hasOwn) by updating your Babel/browserslist config to target modern browsers only.

0Poor

What This Score Means

A score of 39 falls in the "Poor" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.

This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.

Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis

This Next.js site has severe performance issues with a score of only 39/100. The biggest problem is an extremely slow Largest Contentful Paint of 12.5 seconds, primarily caused by a redirect from the non-www to www version that adds 780ms delay, followed by render-blocking CSS files and excessive unused JavaScript (756 KiB). The site also suffers from poor caching policies and network dependency chains that create a waterfall effect, with the main thread being blocked for 2.8 seconds by JavaScript execution. Eliminating the redirect, optimizing JavaScript bundles, and implementing better caching could easily improve the score by 40+ points and dramatically enhance user experience.

Other Optimization Recommendations

Eliminate Redirect and Optimize Server Response

High Impact+25 points estimated

Why It Matters:

The redirect from commissions.gg to www.commissions.gg wastes 780ms and delays both FCP and LCP by 800ms each.

How to Fix:

Configure your DNS/hosting to serve www.commissions.gg directly without redirects. In Next.js, add permanent redirects in next.config.js for the non-www domain. Enable text compression (gzip/brotli) on your server to reduce document latency by an additional 70ms.

Optimize Critical CSS Rendering

Medium Impact+12 points estimated

Why It Matters:

Render-blocking CSS files delay FCP by 750ms and contribute to the poor initial paint performance.

How to Fix:

Inline critical CSS for above-the-fold content directly in your Next.js pages. Use next/dynamic with ssr: false for non-critical components that load heavy CSS. Consider extracting font CSS to a separate file and preloading it with <link rel='preload'> in your Next.js _document.js.
