>> PyDict_Copy creates a new empty dict object and then inserts key/values into it one by one.

> Why not creating a "preallocated" dict in that case? _PyDict_NewPresized()

I don't think it's related to the proposed patch.  Please take a look at the PR.  `_PyDict_NewPresized` and inserting entries one by one will not be faster than a `memcpy`.
