Is it delightful? Are the interactions smooth and natural, free of lag?.

Is it usable? Can users interact with the page or is it busy?.

Is it useful? Has enough content rendered that users can engage with it?.

Is it happening? Did the navigation start successfully? Has the server responded?.

To help ensure that the metrics are relevant to users, we frame them around a few key questions: Over the last few years, browser teams have been working to standardise a set of new metrics and APIs that more accurately capture the performance of a web page.

However, this moment doesn't necessarily correspond with what the user cares about. In the past, web performance has been measured with the load event. Lighthouse and PageSpeed Insights capture a few key metrics: First Contentful Paint, Speed Index and Time (Image credit: Addy Osmani) Note: Public data sets like Chrome User Experience Report (opens in new tab) and performance tools like the PageSpeed Insights speed score report this type of data. Enables correlation to business key performance indicators.Captures true real-world user experience.Field dataДЇield data (also called real user monitoring, or RUM) is performance data collected from real page loads your users are experiencing in the wild. Note: Tools like Lighthouse and WebPageTest (opens in new tab) collect this type of data. Cannot correlate against real-world page KPIs.Might not capture real-world bottlenecks.Provides reproducible testing and debugging environment.End-to-end and offers deep visibility into the UX.

Helpful when it comes to debugging any performance issues.This offers reproducible results and debugging capabilities to help identify, isolate and fix performance issues.

Lab data is performance data collected within a controlled environment with predefined device and network settings. A score of 90 or above is considered fast and 50 to 90 is considered moderate. This score is determined by running Lighthouse to collect and analyse lab data about the page. Performance scoreДЄt the top of the report, PSI provides a score that summarises the page's performance. Field data is useful for capturing true, real-world user experience but has a more limited set of metrics. However, it may not capture real-world bottlenecks. Is useful for debugging performance issues, as it is collected in a controlled environment. PSI provides both 'lab' (Lighthouse) and 'field' data about a page.
