We have 2 PC with Ubuntu 12.04 and connect with 1000M/bit cable. Then start iperf on both PC and get 900m/bit speed in iftop util.
But when on 1-st PC setup PPPoE server and on 2-d PC PPPoE client, and direct iperf in PPPoE, we get only 430 m/bit.
Is it normal that PPPoE on linux so slow? Is any way to get speed as in direct connection or nearly?
