Figure 1. Performance Viewer
The Performance viewer is divided into two views:
- The top view presents function performance data in the Summary table. It displays
the count and invocation information for each function that executes during the measurement,
enabling you to compare the relative data for various portions of your target program. The
information in the Summary table can be sorted by column in ascending or descending order.
Click the column header to sort the corresponding data.
The following table explains the fields of the Summary table.
Table 1. Field description of Summary table Field Description Function Name Name of the function that has executed. Num Calls Number of times the function has executed.

Avg Inclusive Average metric count during execution time spent from function entry to exit. Percent Callee Percent of total metric count during the time the selected function is the caller of a specific callee. The data is also shown in the Caller pie chart. Percent Caller Percent of total metric count during the time the selected function is the callee of a specific caller. The data is also shown in the Callee pie chart.
