What does "Origin Summary" mean in this PageSpeed Insight report?

I recently noticed that Google updated the PageSpeed Insight report page. There is an "Origin Summary".

What does it exactly mean? Why it's slightly different than the field data?

Solution

  • If the page you are testing has enough visitors you will see your "field data". That is real world performance for that page

    The origin summary is real world performance data for all pages on the domain where there is enough data.

    Basically it is page performance (Field Data) vs site performance as a whole (Origin Summary).
