You can get this as well from https://speed.python.org/comparison/
and https://speed.python.org/timeline and looking at this, I think there
is something worrying indeed:
Startup time has increased by ~ 30 % between 3.5 and 3.6 again. More
specifically, all this increase happened between Sep 09 and Sep 15.
I have no clue why that is, but it is definitely the biggest effect far
