Boost.Python is a little slower than wrapping directly using Python C-API, 
especially in very simple cases like yours. (It is a variant of the 
abstraction penalty.) However, it is hard to believe that it is 4x slower. 
Would you mind posting complete compilable examples so that we can take a look 
at it?
