Hi Guys
I have a CCR1009 and use it as a PPPoE Server. A speed test server setup up at the combo port.
However, performance is unstable. The download speed is around 700~1000M, the upload performance is near half of the download speed, approximately 450~500M. When the connection change to IPoE, the client can achieve full speed(1G/1G) .
The L2 structure as the picture below. QinQ adopted in this network.

PPPoE Server set up on the inner vlan.

Client 20 PCs (Core i7 6700, 8GB, RTL gigabyte nic with the newest driver)
No Queues, No dynamic routing protocols, No speed limits on the radius.
Filter: 10 rules NAT:9 rules Mangle:5 rules
