Performance of Woodstox StAX vs Java SAX

Hi,

I am a newbie to this group…. Before I start actively using this parser, I have a query regarding its performance..

As per the parsing benchmarks reported at ….

http://www.xml.com/pub/a/2007/05/09/xml-parser-benchmarks-part-1.html?page=1

The performance of Woodstox StAX is always better than even the Java SAX Implementation.

Any particular reason for the results to be like this?

Did anyone of you do similar kind of performance benchmarking of C/Java based parser w.r.t to Woodstox.

Thanks!!
