A few years ago, when I was still profiling these things, Java-based
DOM implementations were relatively slow to start up with large
documents, even when the the documents fit in memory easily.  Perhaps
Michael and other DOM implementors have found ways to work around the
problem, or Java VMs have gotten faster at allocating new objects.

I've been messing around with something even closer to the metal (and
more efficient) than SAX, just for fun.  If anything comes of it, I'll
post and let everyone know.

All the best,
