I do have a complication in this area. I normally use a demand loaded DOM so
that the parse and transform stages are actually interwolven, this helps
I/O. I can seperate the stages but the code is optimised for demand loading
and has additional execution costs because of it.

Perhaps an alternative is to measure performance on increasingly large input
documents to show the memory scalability of a processor. I do have a
personal interest here in that I also have a paged DOM almost ready to go on
which you can control the memory usage. In this model a kb/kb figure
wouldn't give a useful insight.
