From the developer:
MacCallGrind helps you visualize profiling data produced by Xdebug thats native on Mac OS X. Call profiling and analysis tells you where your code is really spending its time, instead of where you think it is, which leads to both performance improvements and a higher quality architecture for your code. Integrates easily with MAMP.
