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 83 ms
time to first byte 32 ms
element render delay 24 ms
resource load delay 8 ms

LCP LAB Simulated vs LCP FIELD

Lab 1.38 s
Field p75 1.58 s

The lab LCP is 0.87× the field p75 — real users likely have below-average hardware or network connectivity.

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

As rendered

2% of pixels differ — they are nearly identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
