Four Dimensions, One Score
Lab performance (Lighthouse)
Google PageSpeed Insights (Lighthouse) runs on desktop and mobile: the performance score, LCP, CLS, TBT and FCP, graded on Google’s own thresholds. Beside it, what real Chrome visitors got: the Core Web Vitals Google ranks on.
Server response & caching
Measured from our servers: time to first byte, whether the page was served from a cache, how many bytes the HTML ships compressed, redirect chains, and whether your CDN’s edge actually served the page.
Asset optimization
Render-blocking resources, minified CSS/JS, modern image formats, lazy loading and total page weight, the hygiene layer between fast and slow.
Platform & xSpeed readiness
Is it WordPress, which caching plugin is answering, and is xSpeed’s MCP endpoint live, because every failing check maps to an xSpeed feature that fixes it.
Measured, Not Claimed
Every figure below is computed from the public scans on this page: latest scan per site, full-rubric runs only.

Every Failing Check Comes With Its Fix
Other speed tests stop at the problem. This one maps each failure to the xSpeed feature that solves it: and if your site runs xSpeed and is connected to your AI through xSpeed Hub MCP, your AI assistant can apply the whole report for you and re-verify the score.
