Browser – Download (Assets, XHR, Pageload)

Request download phase indicates time browser is receiving response from the backend system. Here we also are making 3 different Root Causes for assets (CSS, images, etc.), XHR and full page load requests.

Root Cause grouping is done using:

  • domain name for Assets and full page load requests
  • shortened URL for XHR requests

To solve the issue in most cases one needs to optimize backend system endpoint (making it closer to the user, eg. using a CDN) or the size of content returned from the system.
