I have a dual core opteron K8 at 1.6GHz serving about 500 pppoe customers and giving them a 100Mb (total) internet link
I configured my ROS 3.30 with about 50 pppoe servers listening each one on a different vlan.
Every pppoe server use a profile with encryption and "change tcp MSS" set to yes
Nothing more, some simple firewall filter rules, a few nat rules and a lot of dynamic mangle rules due to "change tcp MSS" configuration (2 for each pppoe user).
My cpu consumption is near 90-95%!!!!
Please point me in which direction I can investigate!
Can help me disable dynamic change of MSS and set a single static rule?
