On my Windows 7 PC with 3.5.2 and 3.6.0b1 installed from the standard python.org builds: >py -3.5 -m timeit -s "d = dict.fromkeys(range(10**6))" -- "list(d)" 10 loops, best of 3: 21.7 msec per loop >py -3.6 -m timeit -s "d = dict.fromkeys(range(10**6))" -- "list(d)" 100 loops, best of 3: 19.6 msec per loop So 3.6 is faster for me.
