A while back, I added some stuff to the detail view to turn
on/off profiling for CPIA events. If you Go to test->Start Profiler,
you'll get a file called 'Events.prof' in the current directory. The nice
thing about this is that it ONLY logs CPIA events as they are dispatched,
and does not profile stuff like mouse movement and so forth. You can
profile events, turn off the profiler, then load up the Events.prof file
in a python session.. from there, you can do everything Phillip describes...
However, I haven't used in a while. I used to be able to say:
>>> from pstats import Stats
>>> s = Stats('Events.prof')
but now I get an exception.. not sure whats up with that?

Profiling in the Chandler UI is pretty simple. From the "Test" menu
select "Start Profiler", and then do whatever it is you want to
profile. Then select "Stop Profiler". This creates a file called
"Events.prof", which you can analyze by opening a Python shell from the
"Test" menu, and then doing something like this (it helps if you maximize
the window):
>>> from hotshot.stats import load
>>> s=load('Events.prof')
>>> s.sort_stats("cum").print_stats(20)
