Just trying to help look around ....
If I see your screenshot,ingdaka, I see ROS 6.45.7 but still some traces of the old way of using switch hardware (ether2-master), it's only the name not the config, but it is probably an upgraded config.
Ether1 is not part of the bridge-port group (it's not slave), and so usually is at the other side of the firewall. Session tracking and even firewall rules may be triggered, using CPU. Just wondering if this is the case.
With dad2312 I see none of this. (all interfaces are part of the bridge). So the switch chip is doing the work. (Atheros7228). Why is it so slow? Store and forward mode (versus cut through mode)? Switch backpressure because of some half-duplex interface? Loop detection or flow control interfering? If have no idea! What do Rx, TX and status counters reveal ?
