----------------------------------------
Hi Angela,
No, I did not get around to doing the tests yet. In addition, I will also have
to go back to KXml regarding a bug I posted
[1].
I would like to keep this issue open because I really think, that it would be a
good idea to (1) improve performance and (2) lower the memory
footprint/requirements.
I will assign this issue to me for the moment, to somewhat take it of your
plate.
Thanks for the reminder.
> Replace Xerces/JAXP based (un)marshalling by KXml2 based implementation

> Key: JCR-1261

> Project: Jackrabbit
> Issue Type: Improvement

> Proposing to replace the current Xerces/JAXP based implementation of XML data
> unmarshalling and marshalling to be replaced by a MXP ([1]) based
> implementation. MXP is an implementation of the XML PullParser API [2] and
> provides a very mall footprint (120KB) and far better performance than Xerces
> (my tests showed around 50% performance increase over Xerces for both
> unmarshalling and marshalling, see also [3]).
> Why do I care ? I would like to include WebDAV functionality into Sling and
> bundle is with as little dependencies as possible ( the xpp3 lib might even
> be bundled into this project to minimize dependencies). In addition, I think
> XML (un)marshalling performance is crucial in any WebDAV solution. For this
> reason, this project can only win if we add a more performing library.
