Joomla site speed
How fast Joomla websites load on a phone, from Google PageSpeed tests of 25 Joomla sites, and which popular ones are slowest. Use it to benchmark your own site, or to find Joomla sites that need speed work.
Real users: 20% of the 15 Joomla sites with Chrome UX Report data are rated fast overall (good loading, responsiveness and layout stability).

Check one site
Paste a website and see what it runs, live, with the source of each value. No account needed. Its mobile speed is measured when an agent runs.
How this is measured
Each site's home page is tested with Google PageSpeed Insights (Lighthouse, simulated mid-range phone on a slow 4G connection) when it's enriched; real-user ratings come from the Chrome UX Report where Google has enough visits. Only sites in the Tranco top million are named. See also websites using Joomla. Updated October 2026.
