Minimize Main Thread Blocking Time

High Impact+15 points estimated

Why It Matters

8.3 seconds of main thread work creates 1,910ms Total Blocking Time, severely impacting user interaction responsiveness.

How to Fix

Optimize your Vue components to reduce forced reflows by batching DOM reads/writes. Use Nuxt's asyncData or fetch hooks to move heavy computations off the main thread. Implement virtual scrolling for long product lists using @tanstack/vue-virtual.

What This Score Means

A score of 33 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 Nuxt/Vue website has severe performance issues with a critically low score of 33/100. The biggest problem is excessive JavaScript execution taking 8.3 seconds of main-thread work, which is blocking user interactions and causing a painful 1,910ms Total Blocking Time. The site is loading 192KB of unused JavaScript and suffering from render-blocking CSS files that delay content visibility by over 4.6 seconds. Reducing JavaScript payloads, removing unused code, and implementing proper caching (currently missing entirely) could dramatically improve performance and user experience.

Other Optimization Recommendations

Reduce Unused JavaScript Payloads

High Impact+19 points estimated

Why It Matters:

192 KiB of unused JavaScript is blocking page load, delaying both FCP and LCP by 900ms with potential 19-point score improvement.

How to Fix:

In your Nuxt config, enable tree-shaking and code splitting. Split the large IGXVVuY5.js bundle using dynamic imports. Configure Swiper to load only needed modules. Use Nuxt's built-in bundle analyzer to identify and remove dead code.

Implement Efficient Asset Caching

Medium Impact+8 points estimated

Why It Matters:

66 KiB of static assets have no cache headers, missing opportunities to improve repeat visit performance and LCP by 500ms.

How to Fix:

Configure your Nuxt server to set long-term cache headers for fonts and images (Cache-Control: max-age=31536000). Use Nuxt's static file handling to automatically version assets. Set up CDN caching rules for your web-stag.dtv.onl domain.
