Re: How to get Octave.app to work 3

[Vic Norton]

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
