I've never found enough time to take detailed metrics, sorry. Maybe<br>
one day? Looking at my performance graphs again:<br>
<br>
Against the official CPython 3.6 (probably .3 or .4) release I see:<br>
1 that is 2.01x faster (python-startup, 24.6ms down to 12.2ms)<br>
5 that are >=1.5x,<1.6x faster.<br>
13 that are >=1.4x,<1.5x faster.<br>
21 that are >=1.3x,<1.4x faster.<br>
14 that are >=1.2x,<1.3x faster.<br>
5 that are >=1.1x,<1.2x faster.<br>
0 that are < 1.1x faster/slower.<br>
<br>
Pretty good numbers overall I think.<br>
