Performance Data

To view performance data:

1. In the Software Analysis view, expand the project name.

   The data source is listed under the project name.

2. Click the Performance hyperlink.

   The Performance viewer appears.

   Figure 1. Performance Viewer
   
   

The Performance viewer is divided into two views:

• The top view presents function performance data in the Function Performance 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 Function Performance table can be sorted by column in ascending or descending order. Click the column header to sort the corresponding data. The table below describes the fields of the Function Performance table.
• The bottom view or the Call Site Performance table presents call pair data for the function selected in the Function Performance table. It displays call pair relationships for the selected function, that is which function called which function. Each function pair consists of a caller and a callee. The percent caller and percent callee data is also displayed graphically. The functions are represented in different colors in the pie chart, you can move the mouse cursor over the color to see the corresponding function. The next following table describes the fields of the Call Site Performance table. You cannot sort the columns of this table.

  Table 1. Field Description of Function Performance Table

  Name	Description
  Function Name	Name of the function that has executed.
  Num Calls	Number of times the function has executed.
  Inclusive	Cumulative metric count during execution time spent from function entry to exit.
  Min Inclusive	Minimum metric count during execution time spent from function entry to exit.
  Max Inclusive	Maximum metric count during execution time spent from function entry to exit.
  Avg Inclusive	Average metric count during execution time spent from function entry to exit.
  Percent Inclusive	Percentage of total metric count spent from function entry to exit.
  Exclusive	Cumulative metric count during execution time spent within function.
  Min Exclusive	Minimum metric count during execution time spent within function.
  Max Exclusive	Maximum metric count during execution time spent within function.
  Avg Exclusive	Average metric count during execution time spent within function.
  Percent Exclusive	Percentage of total metric count spent within function.
  Percent Total Calls	Percentage of the calls to the function compared to the total calls.
  Code Size	Number of bytes required by each function.

  Table 2. Field Description of Call Site Performance Table

  Name	Description
  Caller	Name of the calling function.
  Callee	Name of the function that is called by the calling function.
  Num Calls	Number of times the caller called the callee.
  Inclusive	Cumulative metric count during execution time spent from function entry to exit.
  Min Inclusive	Minimum metric count during execution time spent from function entry to exit.
  Max Inclusive	Maximum metric count during execution time spent from function entry to exit.
  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.
  Call Site	Address from where the function was called.

You can move the columns to the left or right of another column depending on your requirements by dragging and dropping. You can perform the Export and Configure table actions on the performance data similar to critical code data. You can also view the previous and next functions of the performance data using the icons available in the lower section of the Performance viewer.
