No, with simple types there is no significant Python code being
executed, although a few Python constructors are run. Building Python
objects, from C or Python, is just slow. It hits the memory allocator
really hard -- every element of your list involves several calls to
malloc().

There are probably a few tweaks which would make it go a little
faster, but not much. I'm not sure it's worth the effort. Do you
really need that much performance from a scripting language?  As soon
as you do any actual work, the slowness of Python will far outweigh
the time spent in omniORBpy.

Cheers,

Duncan.
