Whoa, that's gonna be useful for FreeNAS.

Does pfSense gain performance with this?

considering it was done by the "owners" of pfSense, I'd say yes.

not yet.

This is about routing, and pfSense is more of a NAT/packet filter platform.

Might be useful for the BSD router project[1].

Olivier is quite excited.

IPv4 only though.

Noted, but it's not difficult to add IPv6

Can it do ECMP?

Not yet.
