Hi Michael.
Thanks for your input.
My (so far) only concern is that I am using DOM everywhere to store XML
Documents, and I don't know, for testing purpose, how to create the TinyTree
from a DOM document easily.
If there is no simple way, I may consider getting to tinytree directly (but
lots of code refactoring needed to get rid of DOM tree, thus I need to be sure
I will get better perfs).
Best regards,
Fabien

Objet : Re: [xsl] Performance with Saxon and Kernow.
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.

Hi List.
I know some very knowledgeable people are members of this list, so I
will ask a question that is not really directly an XSL one.
I am using Kernow (1.6.1, Saxon 9.1.0.3 Basic) for testing my XSL
Transforms. When using the same XML file and XSL template, the
transformation is done in 31 seconds.
When I use Saxon (9.2 HE) in my Java Servlet (within Tomcat), The same
transformation is measured at 65 seconds (same computer, everything is
local).
The only difference is that the source is a file in the first case, and
an XML Document in the second (so StreamSource (I assume in Kernow) in
the first case and DOMSource in the second).
I am using javax.xml.transform.Templates for caching XSL, but it doesn't
improve things...
Anything I should have a look at ?
Thanks in advance,
Best regards,
Fabien
