PCA collects performance information on your
application and lets you view that information
to observe the runtime characteristics of your
application, such as:
o What parts of your application are executed the most
o What parts of your application are compute-bound or
I/O-bound
o What areas of your application are, or are not,
executed by tests
o What the dynamic call relationships are among the
routines in your application
o Where page faults occur
o Where you use system services
With this information, PCA helps you pinpoint important
qualities of your application, such as the location
and nature of performance bottlenecks, or how effective
your test coverage is.
