# Installed application — Performance page

The installed application performance section presents details on the location and app version, total number of crashes and freezes, the CPU, memory, and I/O performance information.

**Note:** Application performance metrics are available for the previous 2 hours, 24 hours, or 30 days. Select the required time window from the drop-down list to update the visualization.

The chart on the right side displays the application performance metrics. The chart on the left side displays the aggregated metric data for the selected time window.

Total number of crashes - Last 2 hours

</td><td>

Total number of crashes in the last 2 hrs. This lists the aggregate value.**Note:** The number of crashes pertains to applications that emit a window app crash event \(event id = 1000\) on crashing such as Microsoft OneDrive, Microsoft Teams, Microsoft Excel, Microsoft OneNote, Microsoft PowerPoint, Microsoft Outlook, and Microsoft Word.

</table>|Field|Description|
|-----|-----------|
|Average CPU usage - Last 2 hours|Lists the average CPU usage.|
|CPU usage - Last 2 hours|The percentage of total processor \(CPU\) capacity consumed by the application.|
|Average memory usage - Last 2 hours|Lists the average memory usage.|
|Memory usage - Last 2 hours|The percentage of total memory or RAM consumed by the application.|
|Average I/O read - Last 2 hours|The average speed at which the application reads data from storage \(for example, when opening a large file\).|
|I/O read - Last 2 hours|The speed at which the application reads data from storage.|
|Average I/O write - Last 2 hours|The average speed at which the application saves data to storage \(for example, when creating log files or saving a project\).|
|I/O write - Last 2 hours|The speed at which the application saves data to storage.|

**Note:** You can filter the performance metrics by either searching by location of the device or by app version running on the device in a selected time period.
