The Client Performance summary report displays page information as reported by Experience Analytics UI Capture. UI Capture enables the capture of client user interface events that do not result in transactions to the web server. This capability requires additional installation and implementation.
To review detailed breakdowns by time period for this report, click a Page identifier in the first column of the report. Top pages are listed in descending order by count. You can change the displayed pages by applying report filters. The total count of client user interface hits is available as an activity report and in the Technical Site Metrics dashboard.
For the Top pages, the following charts are displayed:
- Render Times - Average render time in seconds. This chart can be useful in determining whether specific pages have any performance issues.
- Broken Images - Average and maximum number of broken image links. Use this chart to determine if individual pages have broken image references. Many pages with broken images can indicate server-side problems.

To access any detail report for a specific URL, click the hyperlink for the URL in the detail table at the bottom of the screen. Data for all of these reports is gathered and submitted in UI Capture.
