Can someone explain me the columns in the output of
IDL> profiler, /report
I am not sure I understand the columns "Only" and "Time". Obviously,
'Only' lists the time spent *only* in that particular routine. But
then adding all those up wouldn't give the total time spent in running
the code. Yet, "Time" lists time which seems closer to actual time
spent in running the code.
I guess, I am more anxious about times in 'Only' not adding up to
total time spent on the code.

I tried it *now*! I didn't know about graphical way. It's nice, but I
am happy with my command-line version, as I can just save the whole
thing in a variable. I always journal my sessions, so
print,outputvariable is always available to see later in that
particular journal file. Thanks for pointing this way to me. It is
cooler than mine :) (Of course, my version of IDL is old. 6.0. So just
wondering if higher versions include 'color-coded' display as well!)

Have you tried the "Profiler View" in the IDL Workbench? It will give
you a graphical display of the profiler results, with a table of the
different times. You can then sort on each column, and export the
results to a text file, etc.
Just a suggestion.

I just wanted to make sure I understand what's going on inside the
profiler's belly. I did use the info to identify the part of the code
that was taking up time. As for system routine, I had issued commands
'profiler,/system & profiler' to profile both -user-defined and system
routines. So it showed time spent in my routines as well as routines
such as sin, cos, rebin etc. And my confusion was, even then it
doesn't add up to total time.
Not worrying, though. Just trying to get a clearer picture.
