A little late, but here it goes:

I tried to use tools from 4Suite some time ago and found them way too slow.
I was using it for XSLT though. It's a good project and the developers
contribute lots to the community, but for my project I switched to Sablotron
and PySablot or Sab-Py ( Can't remember which). That increased the speed
alot. 4Suite is AFAIK pure python so it's probably alwasy going to be slower
than a parser implemented in C/C++.

You can use expat directly, that would increase your parsing a great deal.
See the docs for tips.
