This URL redirects to https://incubator.apache.org/projects/annotator.html.

Lighthouse follows the redirect, so the numbers below describe the destination page, not this one. The redirect is temporary (302/303/307), so it is treated as a detour rather than a move and history stays here.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

Metrics LAB

No field data: the Chrome UX Report is not being collected for this project, so every figure below is from the Lighthouse run.

Metric Lab Simulated
Value Change / range Trend
LCP CWV (estimate) Largest Contentful Paint 3.17 s needs work ↓ -4 ms (-0.1%) 3.16 s – 3.17 s
INP CWV Interaction to Next Paint — field only, no lab run can measure it n/a —

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.
