Reduce JavaScript Execution Time

Generic SiteScore: 48/100Analyzed January 2026

Reduce JavaScript Execution Time

High Impact+25 points estimated

Why It Matters

JavaScript execution takes 5.0 seconds and blocks the main thread, severely impacting TBT and user interactions.

How to Fix

Code-split the 413KB main bundle (a3319169-bfd38be0eee3c695.js) using Next.js dynamic imports. Remove unused JavaScript - 80% of the main bundle and 61% of Google Tag Manager are unused. Defer non-critical scripts and implement lazy loading for components below the fold.

What This Score Means

A score of 48 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 website has poor performance with a score of 48/100, indicating significant user experience issues. The biggest problem is excessive JavaScript execution taking 5.0 seconds to process, which is severely blocking the page and causing a painfully slow Speed Index of 18.6 seconds. The site is loading 6.2MB of data with massive unused JavaScript (1.3MB wasted) and inefficient image delivery that could save 462KB, while the server response time of 820ms is also problematically slow. Reducing JavaScript payloads, optimizing images with modern formats like WebP, and improving server response times could dramatically improve performance by several seconds and boost the score by 30+ points.

Other Optimization Recommendations

Optimize Server Response Time

High Impact+18 points estimated

Why It Matters:

The initial document takes 820ms to load, delaying both FCP and LCP by 700ms each.

How to Fix:

Implement server-side caching for your Next.js application using Redis or Vercel Edge Functions. Enable compression (gzip/brotli) on your server. Consider using a CDN like Cloudflare or Vercel's edge network to reduce latency. Optimize database queries and API responses.

Fix Image Delivery Performance

Medium Impact+12 points estimated

Why It Matters:

Images are oversized and unoptimized, wasting 462KB of bandwidth and slowing page load.

How to Fix:

Use Next.js Image component with proper responsive sizes - your images are served at 720px but displayed at 298px. Configure your CDN (weave-living.com/cdn-cgi) to serve WebP/AVIF formats automatically. Set appropriate quality levels (60-75) and implement proper srcset attributes for different screen sizes.
