AI Performance Analysis

This website has poor performance with a score of 42/100, indicating significant issues that are hurting user experience. The biggest problem is excessive unused JavaScript code, which is wasting 841 KiB of data and slowing down page loading by over 1.2 seconds. The site takes 22 seconds to become fully interactive and has a sluggish Largest Contentful Paint of 5.3 seconds, primarily caused by render-blocking CSS files and oversized images that could be compressed or converted to modern formats. Removing unused JavaScript from HubSpot tracking scripts and Google Analytics, along with optimizing images and deferring non-critical CSS, could dramatically improve the performance score and make the site much faster for visitors.
