The number of messages to be moved per second (the message movement rate). You can use this field to define a
fixed message movement rate. The maximum value for messages per second is 500. If this field is left blank, the
system will optimize the rate based on the queue message backlog size, which may vary throughout the duration of
the message movement task.
