I was happily using my ADSL modem in bridge mode with my RouterBOARD for two years. The speed of the PPPoE connection was always as expected (8 Mbit/s). Now after upgrading to VDSL, I have a new modem. I have configured it to run in the bridge mode, but with RouterBOARD the maximum speed I get is only 13 Mbit/s, whereas if I configure pppd on my Linux server, I get 20 Mbit/s. The "official" speed is 25 Mbit/s, but noone has really attained that speed.
I have no queueing or speed limiting or anything else configured on the RouterBOARD and the CPU utilization is low. There is just no obvious reason for the speed difference.
