Sorry Brett.

How tests were ran? There are two implementations of ElementTree, accelerated and non-accelerated. xml.etree.ElementTree by default is accelerated in Python 3, but non-accelerated in Python 2.

$ python2.7 bm_elementtree.py -n 7 --take_geo_mean 
0.463665158795
$ python2.7 bm_elementtree.py -n 7 --take_geo_mean --etree-module=xml.etree.ElementTree
5.46309932568
$ python3.4 bm_elementtree.py -n 7 --take_geo_mean --etree-module=xml.etree.ElementTree
0.813397633467649
$ python3.4 bm_elementtree.py -n 7 --take_geo_mean --etree-module=xml.etree.ElementTree --no-accelerator
5.31174765817514

If run the test with the same options --etree-module=xml.etree.ElementTree, it will use accelerated implementation in Python 3 and non-accelerated in Python 2.
