Dynamic is pretty slow as well since it involves reflection. What is
the real type of the object you are returning, is it a function or
something? You may want to save it off as a delegate instance instead
of dynamic of that is the case.

I compile the script once and then I save a python object in a dynamic
variable on c#. Then I access the rest of the python code from there all
the time.
