Setup

File test.m contains function test()
- Function take one float parameter
- returns one hardcoded float parameter
Python code calls octave.test(value) using oct2py.

Observation

I am observing an execution times of 1.5 seconds
The first call is 2.0 seconds as expected per Octave documentation

Things I've tried which were unsuccessful

Adding mlock (); to the function script
Using get_pointer() and calling with the pointer

Why does it take so long to call a simple function?
Could something be misconfigured?

A response in the Octave forum said he could duplicate this behavior on Windows and Linux.
It appears to be a limitation in Oct2Py.

I have worked around this issue by spawning the 'octave' command line tool and parsing stdout. This takes just 125 milliseconds.
