I'm not sure why you think it was the wrong choice. If Stem isn't
providing you the performance you want then seems like speeding it up
is the right option rather than writing your own parser. That is, of
course, unless you're looking for something highly specialized in
which case have fun.

Nick improved parsing performance by around 30% in response to this...

Between that and turning off validation I'd be a little curious where
the time is going if it's still too slow for you.
