Quantify collects a complete, accurate set of performance data for your program and its components, including threads, and helps you find exactly where your program spends most of its time. To profile a program's performance:
Instrument and run a program with Quantify to collect performance data.
Analyze the performance data.
Run the program again and compare runs to find performance changes.
Notes:
You can use Quantify in automated testing.
If Quantify was
installed on your system as a component of Rational PurifyPlus, you must
license PurifyPlus in order to use Quantify:
To do this, source or run the file <installtion_dir>/purifyplus_setup.csh or <installation_dir>/purifyplus_setup.sh, depending on the shell you are using. For example:

or
$. /opt/rational/purifyplus_setup.sh
You can include the appropriate commands in your shell start-up script.
