If you're comparing the speed of scripts that have a large amount of
crossings of the cpyext layer (i.e. crossings between Python code and
CPython C extension code), then yes, it's expected to be much slower.
The speed improved a lot recently, which means it is now *much slower*
instead of *very, very much slower*.
It makes no sense, now or in the future, to use PyPy in the hope to
speed up a script that does _only_ lxml stuff with almost no Python
code running in-between.

This is more annoying. Can you give us a way to reproduce this?
