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.
