Simple queue with multiple target addresses

How is it work? If i define simple queue with two or more target addresses it will share queue bandwith with those addresses or just multiple two or more queues for simple targets?

example :

add name=“user1”
target-addresses=172.16.0.1/32,172.16.0.2/32,172.16.0.3/32
dst-address=0.0.0.0/0 interface=all parent=none direction=both priority=1
queue=default/default limit-at=1024000/1024000 max-limit=1024000/1024000 burst-time=16m39s/16m39s
total-queue=default disabled=no

Is it work as three queues with 1024kb bandwith or share 1024kb per three targets ?

It will share the bandwith between target addresses.
