Controlling Data Collection (Performance Profiling)

Related Topics

Quantify allows you set the level of detail at which data is collected for all parts of your program before you run it.

You can also control data collection as your program runs. You can pause and resume data collection to check the performance of specific routines, or take a snapshot of the current data to examine performance in stages.

This section of the Quantify help system provides information about different ways you can control data collection.
