What LCP is made of observed, unthrottled

A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 3.12 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

element render delay 91 ms
time to first byte 22 ms
resource load duration 22 ms
