    set Py_OptimizeFlag to 1 for -O, and 2 for -OO.  Do this prior to 
calling Py_Initialize();

    You can also improve your startup time by setting
Py_NoSiteFlag = 1...assuming you don't need to load site.py

    for example:

extern int Py_OptimizeFlag;
extern int Py_NoSiteFlag;
...
if( !Py_IsInitialized() ) {
    Py_OptimizeFlag = 2;
    Py_NoSiteFlag = 1;
    Py_Initialize();
}
