Yes, that's because of fastpath (aka hardware NAT).
Not so long ago I compared the performance. When fastpath is enabled
(e.g. EdgeOS) you get almost wire speed NAT (~900Mbps, TCP). Without
that I got ~270Mbps.
But the question is, do you really need wire speed NAT? If you do need
then you are probably not a SOHO user.
Anyway... I'm not aware of any open source implementations of fastpath
driver for octeon family. Maybe it's worth to start bugging cavium
itself or device manufacturers so they release at least reference
driver for fastpath :)
