Here are the results Dimitri.
Octave Benchmark 2 took a total of 10.59 seconds with the shebang line
(1) #!/usr/local/bin/octave
[octave-2.9.9]
and a total of 36.54 seconds with shebang line
(2) #!/Applications/Octave.app/Contents/Resources/bin/octave
[octave-2.9.13 from Octave.app]
The complete results of the two tests are appended to this letter.
One idea about the slowness of octave-2.9.13. According to the
preambles (below), octave-2.9.9 is configured for powerpc-apple-
darwin8.8.0 and octave-2.9.13 is configured for powerpc-apple-
darwin7.9.1. I'm not sure if this is relevant, but there it is.
Regards,
Vic

Vic,
If you still have both version could you run the benchmark:
http://www.sciviews.org/benchmark/Octave2.m (you may need
http://www.sciviews.org/benchmark/gcd2.m)
and post the results?
Sincerely,
Dmitri.
