Different steps in the UI that can be measured by the WPT

WebPageTest General Discussion
1

Hello,

There are different milestones while any web page is loading. For example:

  1. First paint (FP) - when the first byte return to the client
  2. First meaningful paint (FMP) - when the site rendered meaningful amount of data that can be presented to the user
  3. Time to interact (TTI) - when the user actually can interact with the site
  4. Visual Complete - When all the data of the screen that the user sees is rendered.

Between all these 4 options, what exactly does the WPT can measure? It is only one of the above options or all of them?

Thanks and regards,
Hezi

Yes, WebPageTest measures all of those along with a bunch of other metrics.
