For example, for a simple class with 9 attributes:
What are results for classes with 2 or 100 attributes? What are results in Python 3.5?
I think you are playing on thin ice. Your results depend on implementation details of the bytecode (in particularly on adding BUILD_CONST_KEY_MAP in 3.6). Other implementations use different bytecode or don't use bytecode at all. CPython can introduce new opcodes in future versions which will change your result drastically. And the straightforward way could become the most fast.
I suggest you to not worry and just wait for more general optimizations in CPython interpreter.
