Then I cannot reproduce the contention you are experiencing, and need
more information to help you.
I am running XEP with 32 concurrent threads on a 4-processors machine,
and there is no contention under flood of .fo documents.

If you see contention, you should be able to see where exactly in the
code it occurs. I also recommend that you run 'straight up XEP', and
the most convenient way to do that is EnMasse/Actinia and a single
Engine (as opposite to multiple JVMs -- EnMasse is capable of both),
and see whether there is any slow-down or scalability issue.

I don't see one in my experiments. And the source code convinces me
that there shouldn't be any unless debugging is turned on, and it is
turned off in the default xep.jar.
