I suppose it depends on what your code actually does. A direct
comparison of execution time for two different machines probably
doesn't make much sense.
Loops and function calls are slow. Built-in functions for numerical
computations that don't involve user-supplied functions are generally
pretty fast.
Perhaps Octave's interpreter will eventually be faster. Would you
like to help make it happen? Funding and code are both welcome.
Thanks,
