lxml is
a lot faster (by virtue of using libxml2 as its backend) but I have yet
to see any real data on the issue. Luckily the API is so similar it
will just require a couple of tweaks like changing the name of the
imported package to test. I'll investigate further.
Well cElementTree, which is really what yum is using, has tested out
faster for the yum use case than libxml2. Like about 3 times faster.
