This URL redirects to https://polyglot-tech-blog.netlify.app/en/.

The site’s front door pointing at the page it serves there — a locale or CMS landing path, not a move. The origin is still the address of the site, so history stays under it rather than forking to a path that depends on where the measurement ran. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

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

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.

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

Scripts disabled
As rendered

97.9% of pixels differ — they have almost nothing in common. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
