help Cloudflare Speed Test FAQ

What does Cloudflare Speed Test measure?

Cloudflare Speed Test reports metrics such as Time to First Byte, DOM Content Loaded, and Fully Loaded time. These help separate server response delays from browser rendering and asset-loading delays.

Can Cloudflare Speed Test show whether Cloudflare improves a site?

Yes. The test can compare loading behavior with and without Cloudflare's proxy in supported cases. That makes it useful for identifying whether caching or edge delivery changes the result.

Where does Cloudflare Speed Test run its tests?

It measures a site from multiple global locations rather than relying only on the tester's local connection. This can reveal regional latency or origin-server problems that a single local test misses.

Is Cloudflare Speed Test the same as a Core Web Vitals audit?

No. It includes useful loading metrics, but a full Core Web Vitals review also examines metrics such as Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift in real-user or browser data.
