The four LCP phases

Across the four LCP sub-parts in Chrome's field data, the largest gap between under 1.2 MB of total page weight and 2.5 to 5 MB of total page weight sits in resource load delay: 360 ms median for under 1.2 MB of total page weight against 502 ms for 2.5 to 5 MB of total page weight. Overall median field LCP is 981ms for under 1.2 MB of total page weight (TTFB 365 ms, load delay 360 ms, load duration 105 ms, render delay 157 ms) versus 1.4s for 2.5 to 5 MB of total page weight.

Total page weight or the framework

Does the framework explain the total page weight difference?

On React, 98% of sites with under 1.2 MB of total page weight total page weight have a good LCP, against 96% of React sites with 1.2 to 2.5 MB of total page weight. Within React, sites with under 1.2 MB of total page weight have a good LCP more often.

How total page weight compounds across cellular connections

Even with HTTP/2 and HTTP/3 multiplexing, transferring several megabytes of scripts, stylesheets, fonts, and images saturates mobile downlink bandwidth and delays critical rendering resources. Across 831 sites (14.8%) under 1.2 MB total transfer, 98% pass field LCP (1.0s median), falling to 91% (1.3s median) on the 12.3% (693) exceeding 5 MB.
