RE: DOM or SAX input faster/more efficient?

If the input comes from source XML, let the XSLT processor build the tree
(i.e., supply a SAX or Stream source) rather than doing the job yourself.
The XSLT processor will usually be able to build a far more efficient
internal tree structure. Only supply a DOM source if your application is
constructing the source tree programmatically (and even then, use SAX if you
can).
