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 413 ms
time to first byte 298 ms
resource load delay 122 ms
element render delay 69 ms

LCP LAB Simulated vs LCP FIELD

Lab 10.93 s
Field p75 1.55 s

The lab LCP is 7.06× the field p75 — real users likely have above-average hardware or network connectivity.
