What are the sizes of your bundles?  Smaller bundles always
show increased throughput - and you need to bench large bundles
to get a "real" idea of throughput.   Here on nstar.rn.com,
we batch with outbound bundles at 1 megabyte - which saves the
long distance caller the additional overhead of sending smaller
bundles - which can add up real fast.
