[issue16465] dict creation performance regression

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

As I understand, the new dict created on every call of function with keyword arguments.  This slow down every such call about 0.1 µsec.  This is about 10% of int('42', base=16).  In the sum, some programs can slow down to a few percents.

Direct comparison of 3.2 and 3.3 is meaningless because of the influence of other factors (first of all PEP 393).
