Dan,

That's a great tool -- thanks for pointing it out. For anyone who ends 
up using it, the combination of the following two methods seems like a 
good place to start:

xdebug_start_profiling();

and

xdebug_dump_function_profile(3);

This will show you the average execution time and the count of executins 
for every function that's called between starting the profiling and 
dumping the data -- pretty useful. It looks like it can also return 
memory usage information. Seems like a good tool; I'm hoping it will 
help me optimize some code in chc_forum for the next release.
