summary
Performance measurement centers on a concrete metric: the Consumer Performance Index at consumerperformanceindex.com which combines synthetic and Pulse real‑user load times, correlates with bounce rate and conversions using about 8 billion beacons, and scores sites 1–100 (top observed score 88). It’s built on the HTTP Archive so quarterly reports can track up to a million sites. Adoption shifts focus from start‑render to user timing marks for hero assets, measured via WebPageTest, SpeedCurve and other RUM tools.
