The Performance Analyzer

The Performance Analyzer is a tool that analyzes the performance data of a program collected by The Sampling Collector or the collect command (see the collect(1) man page). It reads in experiment files generated by the Sampling Collector, and provides you with a number of ways of looking at and manipulating the experiment data, so you can locate program execution bottlenecks and analyze and improve program performance.

To use the Performance Analyzer, you must load an experiment into the Analyzer Window. See Loading an Experiment for instructions on how to do this. This is done automatically with the last experiment collected if you open the Analyzer window from the Sampling Collector Window.

Once you have loaded the experiment, you can examine and manipulate the following types of data:

• Function and Load-Object Metrics (including clock-based profiling, caller-callee metrics, synchronization wait tracing, hardware-counter overflow profiling, and annotated source and disassembly code)
• Sample Overview Information
• Execution Statistics
• Address-Space Information

For information on how to display this data, see Switching Data Displays.
