I can not confirm performance regression in 3.8.0.
$ time ~/pyenv/versions/3.7.3/bin/python permutations2x2 --max_depth 6 | egrep
"^# Total_Time" ; time ~/pyenv/versions/3.8.0/bin/python permutations2x2
--max_depth 6 | egrep "^# Total_Time"
# Total_Time: 50.24
real 0m50.665s
user 0m49.729s
sys 0m4.354s
# Total_Time: 47.97
real 0m48.502s
user 0m47.380s
sys 0m4.506s
I suspect that this is a binary specific issue.
Would you try "perf record python ..."?
