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 (2026-08-31 → 2026-09-27), url-level.

TTFB Time to First Byte 627 ms good ↓ -1 ms (-0.2%) 627 ms – 628 ms 418 ms good 90.5% 6.7% 2.9%

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 18.84 s
resource load delay 1.19 s
time to first byte 584 ms

LCP LAB Simulated vs LCP FIELD

Lab 8.21 s
Field p75 2.38 s

The lab LCP is 3.44× the field p75 — real users likely have above-average hardware or network connectivity.

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

Scripts disabled
As rendered

12% 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.
