The LOAD_GLOBAL bytecode has a fast-path when globals and builtins have exactly the type 'dict'. It calls the _PyDict_LoadGlobal() function.
I propose to implement a similar optimization for LOAD_NAME, see attached patch.
The patch also fixes LOAD_GLOBAL and LOAD_NAME bytecodes when locals, globals or builtins are not exactly the type 'dict'. It clears the KeyError before trying the next PyObject_GetItem().
The patch changes also _PyDict_LoadGlobal() to call PyObject_Hash() if the hash was not computed yet. It might make it a little bit faster. |
