Content 
I profiled dict[str, int](a=1, b=2), and it looks like a decent chunk of time comes from PyUnicode_New as used by PyObject_SetAttrString.

You could also try replacing PyObject_SetAttrString with PyObject_SetAttr and adding "__orig_class__" to the global strings with Tools/scripts/generate_global_objects.py, probably for a later PR.
