Sucuri Load Time Tester

Sucuri Load Time Tester measures website loading and performance signals, including First Contentful Paint, Largest Contentful Paint, and fully loaded time. These results help identify pages or assets that may need optimization.

First Contentful Paint records when the browser first displays visible content. Largest Contentful Paint focuses on when the largest visible content element has loaded, which is often more useful for judging perceived page readiness.

It can point to performance problems and provide data for investigation, but a timing result alone does not prove one exact cause. Slow images, scripts, hosting response, or third-party services may each need separate checking.

No. Results can change with the test location, network, device, caching, and server load. Comparing repeated tests under similar conditions gives a more useful picture than relying on one run.
