PPPoE internet speed on 70G/90G?

[banave]

I'm looking to purchase an FTTP internet circuit 1000(DL)/100(UL), the ISP authenticates over PPPoE.

I haven't PPPoE'd through a firewall in years, and remember there being a significant performance penalty back then - as I believed it couldn't be offloaded to ASIC (probably still the case). Trying to avoid needing another piece of equipment.

Does anyone running either the 70G and/or 90G know if there is a big performance penalty? (and can share stats please?)

Thanks!

Colleagues of mine use a FortiGate 40F which can do Gigabit (920 mbit) on PPPoE
70G and/or 90G should be better, right?
