+### Analyze multi-process performance
+
+Starting in Visual Studio 2022 version 17.13, you can analyze multi-process data in the CPU Usage tool. This makes it easier to analyzer performance for multi-process apps such as .NET Aspire. This features allows you to distinguish and analyze CPU utilization across processes within a single session, which provides clearer insights into resource consumption.
+
+You need to collect multi-process data before you can analyze it. To collect the data, select **Collect data from multiple processes** for the CPU Usage tool in the Performance Profiler.

+
+The timeline graph showing your app's CPU use displays performance data with distinct color coding for each process. The graphs are displayed as stacked area charts.

+
+You can filter processes using a dropdown on the top left of the CPU timeline graph. When you select or deselect a process, the profiler summary page and detailed reports are updated based on the new selection(s), enabling more precise analysis.
