Tyblog | Building my ideal router for $50

@RickS - what I did is change my pppoe configuration template. It had a “pty” line calling /usr/sbin/pppoe with some flags, which translates to running pppoe as a userland process. (When I was on VDSL, it worked just fine; when I connected to FTTH, CPU went to the roof and performance was blocked.)

Instead, I –

  1. Made sure my kernel is compiled with PPP and PPPOE (as modules, in my case, but that’s unimportant)
  2. Remove the pty lines from my pppoe configuration
  3. Add “plugin rp-pppoe.so” to that configuration

This makes pppoe use the kernel module. Performance upped 5-7 times once I did that.

Hope this helps!
