You don't really want more children than you need, it will just waste
memory mostly. If you have restricted RAM available, then be very careful
not to have too many children.

The queue scan interval only makes a difference when there is almost
nothing going on. If there are any messages ready for processing then they
will be processed immediately. The queue scan interval is only used when
the queue is found to be completely empty, it waits a few seconds before
scanning the queue again so as not to needlessly waste CPU.
