Question about numbers of connections

[Espartano]

Hi folks, I have a question about PF over FreeBSD.

I would like to know how many connections can manage pf with 256 Mb of
ram, I think that PF can manage a lot of connections  because it only
needs to negotiate the firts package of the connection then it would
acept or deny the rest of connection's packages, but I don't sure if
my thinks are right or not, anybody could say me if my argument is
right or not?

I have an Alix machine based in Geode LX800 processor with 256 Mb of
ram, and I would like to know if I can do a firewall (PF) with my alix
machine and  put it in a place with a lot of traffic without troubles.

Sorry for my english it's very poor :(

Thanks a lot.
