Timings Added to History Graph and More Updates

This article may contain outdated material

The features outlined in this article are still available. However, the content pertains to the legacy version of GTmetrix.

We’ve added the rest of our timings to the history graph for a complete visualization of your performance.

DOM Interactive, DOM Content Loaded, First Paint and First Contentful Paint are now graphed on the History.


Joining Time to First Byte (TTFB), Onload and Fully loaded times, four more timings are now available for History graphs:

  • First Paint
  • First Contentful Paint
  • DOM Interactive
  • DOM Loaded

Each timing can be toggled depending on the metrics that matter to you.


Toggled timings will be kept even after you’ve exited the page.
