There was never a working profiler program for MorphOS. Since we got used to it it wasn't considered to be a problem. But it's nice to know which part of your program takes much CPU time and which part can be optimized for biggest speed gain. This is a reason for which libprf was created.
This library allows you to get a statistics for running program. It use a small trick from gcc, so can only be used with applications compiled with it (Works for both 2.95.3 and 2.95.4).
