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 1.14 s

time to first byte 160 ms

resource load duration 26 ms

resource load delay 18 ms

LCP LAB Simulated vs LCP FIELD

Lab 6.37 s

Field p75 2.10 s

The lab LCP is 3.03× the field p75 — real users likely have above-average hardware or network connectivity.
