In this latest update, we’ve made some changes to the Breakdown section of the reports page to allow for a more streamlined user experience.

The new “History” tab

The “History” tab contains all of the graphs that were previously under the “Performance History” tab. We’ve added tool tips to the nodes that allow you to:

  • View the highlighted report (if you’re not already viewing it)
  • Compare the highlighted report to the currently viewed report
  • Delete the highlighted report

This provides our users with a more visual way of keeping track of past reports.

Tool tips now appear on each node for every graph.

The new “Timeline” tab

GTmetrix now generates a waterfall graph for each report. You can easily see how your site elements load and troubleshoot any problem areas that you may see. You can view a full version of the graph by clicking “View Larger Version” on the top right-hand corner of the graph.
