The Chrome User Experience Report provides user experience metrics for how real-world Chrome users experience popular destinations on the web.
The Chrome User Experience Report is powered by real user measurement of key user experience metrics across the public web, aggregated from users who have opted-in to syncing their browsing history, have not set up a Sync passphrase, and have usage statistic reporting enabled.
More metrics are now available in SpeedFactor with colour coding and contextual help. All these metrics are saved and displayed in a daily graph.
