Research direction
The issue names no repository files or tests. Start by reproducing the comparison between native Python field access and access to a converted C++ class field, then trace the Boost.Python attribute-access path; done means explaining the overhead and identifying a validated improvement.

Description
What is boost python actually doing when accessing a C++ class field from python. I could live with the overhead from calling functions but just accessing int/bool fields is 10-20 slower than a native python class.
Tested this by making two identical classes one in native python one in C++ and accessing a single integer field. Access in the C++ class seems to be 10 times slower. Can I do anything to improve this ?
