[New-bugs-announce] [issue28852] sorted(range(1000)) is slower in Python 3.7 compared to Python 3.5

[STINNER Victor]

New submission from STINNER Victor:

Follow-up of my comment http://bugs.python.org/issue23507#msg282187 :

"sorted(list): Median +- std dev: [3.5] 17.5 us +- 1.0 us -> [3.7] 19.7 us +- 1.1 us: 1.12x slower (+12%)"

"(...) sorted(list) is slower. I don't know why sorted(list) is slower. It doesn't use a key function, and so should not be impacted by FASTCALL changes made since Python 3.6."
