That wouldn't surprise me. XOM does quite a bit more work when building 
than most parsers do.

I think it will be quite a bit faster, maybe as much as a factor of two 
on average so if it was only 10% slower before, it should really smoke 
the competition now. :-) API and feature-wise 1.1 is essentially 
complete. I'm just tweaking the performance as time permits. My plan is 
to release 1.1 shortly after xml:id goes to final rec, since that's the 
only unfinished standard 1.1 depends on.
