= Problem = If you specify the '''optimize''' option in your ''setup.py'', this will only be used for the compiling of the needed modules, not for your main module!<
>For example if you have the following ''setup.py'': {{{ #!python from distutils.core import setup import py2exe setup( options={"py2exe":{"optimize":2}}, console=["beep.py"] ) }}} The bytecode embedded in the resulting .exe will not be optimised. = Solution = To get optimized bytecode, you need to call the ''setup.py'' like so: {{{ python -OO setup.py py2exe }}}
