Lighthouse follows the redirect, so the numbers below describe the destination page, not this one. Not yet confirmed as a move; it needs to lead to the same place on several consecutive runs first.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

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 1.23 s
time to first byte 138 ms

LCP LAB Simulated vs LCP FIELD

Lab 13.50 s
Field p75 1.44 s

The lab LCP is 9.38× the field p75 — real users likely have above-average hardware or network connectivity.
