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.

resource load duration 183 ms

element render delay 36 ms

time to first byte 22 ms

resource load delay 10 ms

LCP LAB Simulated vs LCP FIELD

Lab 4.53 s

Field p75 1.12 s

The lab LCP is 4.04× the field p75 — real users likely have above-average hardware or network connectivity.
