[Haskell-cafe] HXT is slow?

Is it just me, or is HXT slow? I noticed that both reading a document from a file, as well as running computations, are exceedingly slow, with simple stuff like 'get the contents of everything with a given class' taking .3 seconds for a 400KB HTML file in Python using lxml and 2 seconds using HXT with tagSoup and compiled with -O2.
