Performance in embeded / extended python

Hi,
I embedded and extended python for a game, and I was REALLY
disappointed by the performances I get...
Every frame of my game ( should be 60 time by second ) I call my
Python logical part from my C game with :
PyObject_CallFunction( LogicalEntryPoint, NULL );
Logical Entry Point being a PyObject* pointing on the name of the
function.
My function do only :
for i in range ( 0, NbTestSprites - 1 ):
ListOfSprites[i].setPos( 100, 100 )
ie it sets the pos of 200 sprites.
ListOfSprites is a tuple of 200 sprites, sprites is a extension class,
and setPos one of its method.
I'm using Swig to extend Python with my C functions ( I Tried Boost
too, but there is even more overhead... )
This is _REALLY_ slow ( i run at around 1 Frame / second on a P733 ).
200 sprites is not so much...
Have someone a clue of something I could have done wrong ?
Can't extended python be faster ?
Any help appreciated,
thanks,
Emmanuel
