The bridge forwarding delay is set to 0 seconds so that forwarding begins immediately when a new interface is added to a bridge. The default delay is 30 seconds, during which the bridge pauses all traffic to listen and figure out where devices are. This can interrupt services when a container is added to the bridge. If you aren't running the spanning tree protocol (off by default) and the bridge does not create a loop in your network, then there is no need for a forwarding delay.
