State of the Union for Speed Tooling
summary
Metrics landings are concrete: First Contentful Paint, First Input Delay, and Time to Interactive are defined and mapped to lab vs field; FID is a field metric and lands as a web perf API in Chrome in Q4/early Q1. Lighthouse 4.0 cuts median runtime about 50% and 90th percentile about 66%. Throttling presets are relabeled (fast 3G → slow 4G). PageSpeed Insights V5 exposes full Lighthouse results and CrUX now covers over 4 million origins.
