This URL redirects to https://fberriman.com/blog/.

The same URL in a different form — a trailing slash — so both are treated as one site rather than two: one history, measured once. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

The measuring machine was faster than most in this project.

Lighthouse benchmark index was 3,458, 39% faster than this project's median of 2,481. CPU-bound metrics — TBT, TTI, main thread work — are affected by this and may have moved without the site changing at all.

Metrics Lighthouse, mobile

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