My original point (printing to console can be quite slow) is supported
by your figures just as much as it is by mine; but the difference
between them is unsurprising, given the number of differences in the
test (list vs iterable range, Linux vs Windows, Py2 vs Py3). So, not
subjective, but still open to huge variation.
