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 (2026-09-06 → 2026-10-03), origin-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 47 ms
resource load duration 36 ms
resource load delay 23 ms
time to first byte 20 ms

LCP LAB Simulated vs LCP FIELD

Lab 1.52 s
Field p75 1.46 s

The lab LCP is 1.04× the field p75 — 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

45.5% of pixels differ — parts of the page change. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
