I used M-x profiler-start RET RET then after a few other operations I did M-x profiler-stop.

Then M-x profiler-report. It doesn't show any profile data.

I am using OSX. Where is profile data supposed to be saved? and what is the file name supposed to be?


You need to use M-x profiler-report before you do M-x profilter-stop. The profiling data is not saved in any file, it's kept in memory.
