They cannot really be compared -- XML is a mechanism for serializing
an object tree, while object trees are a mechanism for compiling XML
documents.  If you write everything out as XML and then read it in
again, of course you'll take a hit, but presumably you don't write it
out unless you have to do something with it (give the information to
someone else, save the state of your object tree between invocations,
or archive the information somewhere).

Think of your object tree as RAM, and XML as the hard drive -- RAM's
usually faster, but the information has to come from somewhere.


All the best,


David
