Metrics LAB FIELD

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

Field figures are the p75 across real Chrome users over a 28-day trailing window (2026-09-09 → 2026-10-06), 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 2.61 s
time to first byte 602 ms

LCP LAB Simulated vs LCP FIELD

Lab 3.84 s
Field p75 1.76 s

The lab LCP is 2.18× the field p75 — real users likely have above-average hardware or network connectivity.

Without JavaScript

This page is client rendered.

Nothing was painted until the scripts ran. This is a web performance and robustness issue!

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

Scripts disabled
As rendered

77.4% of pixels differ — the page changes substantially. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
