As Nathan Kurz's posting to the perl-xml shows, there is a bottleneck in just
the parsing of the XML without bringing callback firing, let alone query
processing into the picture.

This is great if your use-case supports it. It is not a general purpose
approach to providing scaleable performance for soft real time systems that
want to incorporate XML parsing.

Once again, I would say that if your "high performance" system can architected
using a "cache the parse+query" approach and the complexity and storage
overheads are acceptable, go for it.  There are alot of "high performance"
systems that wont be amenable to this approach.
