I got an Orange Pi R1 Plus LTS board. It has a quad-core A54 CPU running at 1.5GHz. I tried running a PPPoE, but got disappointing rate of around 450Mbit, with CPU utilization around 50%. With plain routing (WAN-to-LAN with out-of-the-box configuration), it was unable to go beyond ~600Mbit, again no sign of CPU maxing out.
Is there anything I'm missing out here or is it too much to expect from such a board to drive a 1Gb PPPoE link?
You're not maxing out one core, by any chance ?
Check by using htop.
