Try -profiler-; it will probably do what you want.  From the help file:

"profiler is a programmer's command that can help in optimizing ado-files
and other Stata programs.  When profiling is turned on, profiler on, Stata
begins keeping a record of each time a program is run and how much time is
spent in the program."

Hope this helps.


BTW, when start a session with -profiler clear- and I haven't run profiler
yet, it crashes.  Just -capture profiler clear- is the way I deal with it.
