The measuring machine was faster than most in this project.

Lighthouse benchmark index was 4,419, 78% faster than this project's median of 2,486. CPU-bound metrics — TBT, TTI, main thread work — are affected by this and may have moved without the site changing at all.

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