I am also on EPB fiber, and can pull about 120mbps on the 100mbps connection with my ERL.
Your config looks pretty good, the traffic control/QoS has the right number of zeros, nothing stands out for limiting the max speed.
Are you running firmware v1.9.0?
Try turning off DPI and any NetFlow exports if enabled.
As an experiment, can you try and see if you can push an iperf/network speedtest at 1000mbps between your two LAN ports? (I've reached 500mbps before, but the hard drives used were a limiting factor.)
