Re: [xsl] Performance with Saxon and Kernow.

[Michael Kay <mike@xxxxxxxxxxxx>]

 I generally tell people that running Saxon using its native tree model 
(TinyTree) is 4-10 times faster than running the same transformation on 
a DOM, so if you are getting a ratio of 2, you are doing quite well.

If you want performance with Saxon, don't use a DOMSource.
