Hi,
Antoine Pitrou asked me to compare Python 3.6 to Python 3.5. Here are results on the speed-python server using LTO compilation (but not PGO):
$ python3 -m perf compare_to 2016-11-03_15-37-3.5-89f7386104e2.json 2016-11-03_15-38-3.6-c4319c0d0131.json -G --min-speed=5 Slower (17):

- nbody: 262 ms +- 3 ms -> 246 ms +- 3 ms: 1.07x faster
Benchmark hidden because not significant (31): 2to3, chaos, (...)
call_method_* slowdown: http://bugs.python.org/issue28618
python_startup slowdown: http://bugs.python.org/issue28637
I didn't analyze results yet.
