Yes, figuring out how to profile Octave would be a first step towards 
trying to reduce the runtime on simple examples such as those used in 
the Julia benchmark.

This has been discussed a few times on the mailing list, and it didn't 
seem easy back then.  Here are a few relevant nabble threads:

-----

June 2014 : me asking for help to build static version of Octave 
instrumented with gprof ; no one answered
http://octave.1599824.n4.nabble.com/For-loop-benchmarks-between-Octave-versions-tp4664522p4665042.html
(I am giving a link to the end of the discussion where gprof is 
mentioned, but the whole thread is about performance and the Julia 
benchmark)

May 2013 : Daniel Kraft asked for advice about using gprof ; Jordi said 
that he had never managed to get gprof to work with Octave ; suggests 
oprof instead

March 2013 : Júlio Hoffimann managed to get OProfile working (but not 
gprof) ; nobody answered on the mailing list
http://octave.1599824.n4.nabble.com/Profiling-GNU-Octave-tp4650637.html

February 2009 : apparently, building a static version of Octave was 
necessary at the time to get gprof to work

These discussions are rather old.  And I could find anything more on the 
wiki.

Did I miss something ?  Does anyone have working recipes to use gprof or 
oprof on recent versions of Octave ?
