This URL redirects to https://www.zachleat.com/about/.

The same URL in a different form — a trailing slash — so both are treated as one site rather than two: one history, measured once. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

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 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), origin-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.

time to first byte 1.16 s

element render delay 312 ms

LCP LAB Simulated vs LCP FIELD

Lab 1.68 s

Field p75 1.05 s

The lab LCP is 1.6× the field p75 — real users likely have above-average hardware or network connectivity.

Without JavaScript

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