I think making more objects immortal by default will reduce the gap, although I am not sure it can be 2%. (I guess 3% and I think it is acceptable gap.) * Code attributes (contents of co_consts, co_names, etc...) in deep frozen modules. * only if subinterpreter shares them. * Statically allocated strings (previously _Py_IDENTIFIER) To reduce gap more, we need to reduce Python stack operation in ceval in some way.
