[jdom-interest] JDOM2 and Performance.

Hi all.

I have put together a 'simple' system for measuring the relative 
performance of JDOM2. The idea is that I need to know whether I am 
improving or breaking JDOM performance as the code evolves.

Currently the metric code is only useful of you compare apples to 
apples, and, in this case, it means processing a single (medium size) 
XML document on my laptop, yada-yada-yada. But, it should be useful as a 
tool to get a feel for what a code-change does.

Already I can see that I probably have an issue in the SAXHandler 
(possibly an issue in JDOM-1.1.2 actually) because 1.1.2 is 5-times 
faster in that area than JDOM2.

I have put together a results page here:


It also describes what each test does. If you are interested in seeing 
the code and what it does have a look here (it is not well documented 
and it is still perhaps evolving):
