XG-7100 1U PPPoE performance?

[FlyingBear]

I'm contemplating an XG-7100 1U for a home installation with the dreaded CenturyLink 1Gbps PPPoE/VLAN service. Has anyone tried this please? I don't know if the Atom processor has good enough single-core performance to give me most, if not all, of the 1Gbps and/or if the workaround tunable net.isr.dispatch=deferred solves the problem? Thanks!
