The measuring machine was faster than most in this project.

Lighthouse benchmark index was 3,398, 37% faster than this project's median of 2,486. CPU-bound metrics β€” TBT, TTI, main thread work β€” 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: passing 2 of 3 assessed from real Chrome users.

Field figures are the p75 across real Chrome users over a 28-day trailing window (2026-09-05 → 2026-10-02), url-level.

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.

element render delay 46 ms
resource load duration 45 ms
time to first byte 29 ms
resource load delay 9 ms

LCP LAB Simulated vs LCP FIELD

Lab 1.45 s
Field p75 1.49 s

The lab LCP is 0.97Γ— the field p75 β€” real users likely have similar hardware or network connectivity to the lab test.

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.
