In this illustration, out of ms were spent in the function body, and the remaining time was spent in other code called by this function. Actual values will be very different depending on your environment. High values in Function Body may indicate a performance bottleneck within the function itself. Skip to main content.

View all page feedback. High values in Function Body may indicate a performance bottleneck within the function itself. To see a higher-level view showing the order in which the functions are called, select Call Tree from the drop-down list at the top of the pane.
Total CPU indicates how much work was done by the function and any functions called by it. High total CPU values point to the functions that are most expensive overall.
Self CPU indicates how much work was done by the code in the function body, excluding the work done by functions that were called by it. High Self CPU values may indicate a performance bottleneck within the function itself.
Modules The name of the module containing the function, or the number of modules containing the functions in an [External Code] node. If you see code in the call tree marked as "broken" code or "unwalkable stack", this indicates that Event Tracing for Windows ETW events were likely dropped. Try collecting the same trace a second time to resolve the issue.
External code are functions in system and framework components that are executed by the code you write. External code include functions that start and stop the app, draw the UI, control threading, and provide other low-level services to the app. In most cases, you won't be interested in external code, and so the CPU Usage tool gathers the external functions of a user method into one [External Code] node.
If you want to view the call paths of external code, choose Show External Code from the Filter view list and then choose Apply. Be aware that many external code call chains are deeply nested, so that the width of the Function Name column can exceed the display width of all but the largest of computer monitors. When this happens, function names are shown as [ Use the search box to find a node that you are looking for, then use the horizontal scroll bar to bring the data into view.
If you profile external code that calls Windows functions, you should make sure that you have the most current. Without these files, your report views will list Windows function names that are cryptic and difficult to understand. For more information about how to make sure that you have the files you need, see Specify symbol. In this tutorial, you've learned how to collect and analyze CPU usage data.
