Load Balancing
From PresenceWiki
This is Load Balancing
A server will be hungry for tasks based on it's Priority, how many tasks it is currently running and
The server priority is set in the presenceconfig.xml and read when teh server starts up.

If the task has excluded servers or a preferred server then Load balancing will take a back seat.
