The measuring machine was faster than most in this project.

Lighthouse benchmark index was 4,387, 76% faster than this project's median of 2,486. CPU-bound metrics — TBT, TTI, main thread work — are affected by this and may have moved without the site changing at all.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

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.

Metric Lab Simulated

LCP CWV (estimate) Largest Contentful Paint 904 ms good ↓ -15 ms (-1.6%) 902 ms – 979 ms

TTFB Time to First Byte 604 ms good ↓ -15 ms (-2.4%) 602 ms – 679 ms

LCP Subparts LAB Throttled

The subparts attribute LCP to your server, resource discovery, download, or rendering. They come from one throttled load, the same one as the filmstrip, so they add up to that load’s LCP rather than the simulated Lab LCP above.

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.
