I really should repeat the performance comparisons I did in the past,
but last time it turned out that
using XML as exchange format wasn't faster nor compacter  than using
java serialization.
But the results varied significantly between tests, I still have to
figure out if variance was caused by different JVM version, different
OS (tested on Windows and linux) or just because the comparison was
badly written.

But nevertheless, XML as exchange format still has the advantages I
mentioned in a previous post.
I will try to create a Log4jXmlLayout for logback really soon.
