The Performance Report shows you a trend of all performance metrics for the real user or synthetic performance on your site. This report has the following components:
Performance Trend Graph
The performance graph shows all of the metrics for your real user or synthetic data trended over the specified time period. The shaded blue area represents the session volume over time. The y-axis shows seconds and you can see how your metrics compare - Onload, DomComplete, Time to DOM Content Loaded, etc.
Filter Option Information
The Filter Option Information section lists the details for the report. Most importantly, it lists the filtering applied to the data so you can ensure you have appropriate context as you're analyzing the report.
Performance Trend Table
The table at the bottom of the report offers you the exact same data from the graph above in a table. Here you can see the value of each metric in the graph over each time bucket, in this case, each hour.
