Felix Meschberger commented on JCR-1312:
----------------------------------------

Performance: kXml is about twice as fast as Xerces for both parsing and 
serializing

Memory Footprint: 
    xercesimpl 2.8.1 Impl: 1.2MB
    kxml 2.2.2: 10KB

To be honest: using kxml instead of xerces requires the additional classes I 
added in the second patch to JCR-1261 [1]. But these are small, and one has 
even been copied ...

To me theses figures are quite impressive.

> Currently the web dav library uses Xerces and DOM to parse and create XML 
> data. This mechanism is well-known but has two major issues: It is slow and 
> it has a big memory footprint. In order to solve these two issues, I suggest 
> to drop the use of the W3C DOM in webdav in favor of something easier and 
> more straight forward to use.
> One candidate could be (out of my head and based on my bias towards KXml) 
> KDOM. See also http://www.kxml.org.ww
> See also JCR-1261 for more discussions on this issue.
