Unveiled at the Chrome Dev Summit in San Francisco, the Chrome User Experience Report is intended to let developers discover how their web apps perform in the wild by providing data collected from the top 10,000 websites.
Introducing the new initiative, the Chromium blog states:
Although current tools allow developers to understand how real-world users experience their own sites, they have never provided insight into comparisons with other sites or macro user experience trends across the web.
To make such comparisons possible the Chrome User Experience Report is a public dataset, on Google BigQuery, of measurements related to user experiences currently including page load metrics, specifically First Paint, First Contentful Paint, DOMContentLoaded, and onload.
All performance data included in the report is from real-world conditions, aggregated from Chrome users who have opted-in to syncing their browsing history and have usage statistic reporting enabled. The initial release is for a sample of ten thousand websites. To access the dataset, you’ll need a Google account and to have created a Google Cloud Project.
This query indicates that 12.3% of page loads achieved FP within 1000-1200 milliseconds (1 - 2 seconds) when loading “http://example.com” on a “mobile” device over a ”4G”-like connection.
A histogram, like the one below for FCP, makes it easier to get an impression of app performance and user experience:
Armed with the information they can obtain from Chrome User Experience report, web developers will be able to gauge how their own websites and apps measure up.
Is this something devs will want to do?
Or is this a Google too far?
