Control Your Analysis

The debugger serves as the data-gathering front end for the Sampling Analyzer. You can control the data collection process with the Sampling Collector window in dbx or the debugger while your program is running. You can collect data only between breakpoints, or you can limit data collection to a particular part of the program. The program run in which you collect data is known as an experiment, and the data file created by the Collector is called the experiment record. You then use the Sampling Analyzer to identify performance bottlenecks in the collected data.

Performance tuning and runtime checking are mutually exclusive processes. You can perform only one or the other at a time. The information you receive from tuning your application can be adversely affected if you try to perform runtime checking simultaneously.
