Metrics LAB

No field data: the Chrome UX Report is not being collected for this project, so every figure below is from the Lighthouse run.

LCP Subparts LAB Unthrottled

The subparts attribute LCP to your server, resource discovery, download, or rendering. Note that the Lab LCP shown above is a simulated throttled estimate.

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

As rendered

0% of pixels differ — they are identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
