The measuring machine was faster than most in this project.

Lighthouse benchmark index was 3,877, 56% 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 FIELD

Core Web Vitals: failing 3 of 3 assessed from real Chrome users.

Field figures are the p75 across real Chrome users over a 28-day trailing window (2026-09-07 → 2026-10-04), url-level.

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.

element render delay 17.66 s
time to first byte 595 ms

LCP LAB Simulated vs LCP FIELD

Lab 12.21 s
Field p75 2.78 s

The lab LCP is 4.39× the field p75 — real users likely have above-average hardware or network connectivity.

92.1% of pixels differ — the page changes substantially. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
