People, you are missing a few points here:

-  if you want to run a DFZ router or do not like flowtables, turn
    them off. There is a kernel option for that.

-  if you use it and it doesn't perform but you have a valid setup,
    tune it.

-  if you are under a (D)DoS your least problem most likely is a small
    performance drop from the extra flowtable lookup, but you'll be
    happy enough if other things do not keel over.

-  For an average FreeBSD thingy that does forwarding, say a pfsense
    box, maybe a router in front of a few subnets with a some web/mail/dns/..
    servers, maybe a box forwarding packets for some SMB, ..
    this, may indeed help.
