Gig wire speed is no problem at larger packet sizes (at all 64K packets,
not going to happen, but that's true of every security device on the
planet). I've seen 3 Gb LACP pushing 3 Gb.

200K states isn't actually that much at all. I see about one box a week at
random with that many or more. In much more extreme examples, several
security consulting and PCI ASV service providers put their scanners behind
pfsense because it's great at handling up to millions of simultaneous
connections, which is either impossible or will cost you as much as a house
with a commercial firewall.
