I'm using xpath on an embedded system (200 MHz arm).  At one point my
XML tree got to be about 100K long.  Because of the architecture of the
system, it is reparsed many times - up to 60 or 70 times per "update".
Each update requires opening the XML file, doing some lookups, and
closing it. The tree is not rewritten. There's some additional overhead,
but even with such a slow CPU each open/lookup/close cycle was taking
maybe 100msec.

So XPath performance is really good.

Linux stuff has made big progress over the competition. When things sit 
and don't start right away, we have a watch, and those poor guys have to 
settle for an hourglass.
