Implement Efficient Asset Caching

Medium Impact+15 points estimated

Why It Matters

Poor cache policies waste 955 KiB on repeat visits and slow LCP by 4.75 seconds.

How to Fix

Configure your CDN to serve JavaScript and CSS files with Cache-Control: max-age=31536000 (1 year) instead of current 1-day cache. Implement versioned URLs or ETags for cache busting. Set longer cache lifetimes for static assets like images and fonts.

What This Score Means

A score of 35 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 travel booking website has severe performance issues with a score of only 35/100, indicating a very poor user experience. The biggest problem is excessive JavaScript bloat - the site loads 354 KiB of unused JavaScript code that delays page rendering by 1.7 seconds, while the main script file alone is nearly 1.8 MB. The site takes an extremely slow 17.1 seconds for the largest content to appear and 17.3 seconds to become interactive, which will frustrate users and hurt conversions. Reducing unused JavaScript, optimizing the 291 KiB of oversized images (including converting a GIF to video format), and improving caching could dramatically improve performance by 4+ seconds and boost the score by 30+ points.

Other Optimization Recommendations

Eliminate Unused JavaScript Code

High Impact+25 points estimated

Why It Matters:

354 KiB of unused JavaScript is blocking page load and delaying LCP by 1.65 seconds.

How to Fix:

Implement code splitting using dynamic imports to load JavaScript modules on-demand. Use webpack-bundle-analyzer to identify unused code in main-thDUzlr-.js and vendor files. Remove unused PrimeVue components and Sentry features not required for production.

Optimize LCP Image Discovery

High Impact+20 points estimated

Why It Matters:

The LCP element isn't discoverable in initial HTML, causing unnecessary load delays.

How to Fix:

Move the loyalty program banner background image from CSS to an HTML <img> tag with fetchpriority='high' attribute. Add preload link for critical images in the document head. Remove lazy loading from above-the-fold images to ensure immediate discovery.
