RUM includes comparison reports that provide greater insight to your users, allowing more flexibility to make before and after comparisons of your site’s performance such as changes made at the Akamai edge or any updates to your infrastructure or application.
Using RUM reporting filters, comparison reports are customizable and display comparison results in the form of a histogram. The y-axis represents the percentage of data points received for each set of boundary values shown on the x-axis. The x-axis represents the boundary values of the time delay, before and after a change to the website. By default, the x-axis is set to 0.5 second intervals. A summary, based on the result of the selected reporting filters, is provided at the bottom of the report.
