AI Performance Analysis
This website has poor performance with a score of 44/100, indicating significant issues that hurt user experience. The biggest problem is excessive render-blocking resources that delay the initial page display by 1.8 seconds, particularly CSS files from WooCommerce plugins and the mega menu. Additionally, the site has an extremely slow Largest Contentful Paint of 19.4 seconds and loads over 6MB of data, much of which consists of unused CSS (214 KB) and JavaScript (527 KB) that could be eliminated. Fixing these blocking resources and removing unused code could dramatically improve loading speeds and boost the performance score by 30+ points.
