I'm sure it's currently much slower, see here:

I'm not sure the quickly patched lxml is as fast in PyPy as it is in
CPython, but there is certainly room for improvements, as I mentioned
before. A substantial part of it runs in properly hand tuned C, after all,
and thus doesn't need to go through cpyext or otherwise talk to PyPy.
