Module Usage
Module usage shows how much of the execution time is spent
outside of the module (from exit to entry). This measurement
gives an indication of how often the module is being used.

Using the
Software
Performance
Measurement Tool
Activity and duration measurements are made with the SPMT in a
five-step process, as follows:
1. Set up the trace command.
2. Initialize the performance measurement.
3. R un the performance measurement.
4. End the performance measurement.
5. Generate the performance measurement report.
These five steps are described in the following paragraphs.
Setting Up the Trace
Command
Before you initialize and run performance measurements, the
current trace command (in other words, the last trace command
entered) must be properly set up.
In general, you want to give the SPMT as many trace states as
possible to post-process, so you should increase the trace depth to
the maximum number, as shown in the following command.
display trace depth 512 <RETURN>
Also it is important that "time" be counted by the analyzer;
otherwise, the SPMT measurements will not be correct.
Activity Measurements
If you wish to measure activity as a percentage of all activity, the
current trace command should be the default (in other words,
"trace counting time < R ETUR N> "). The default trace command
