Well, the 30GB is really just an example of the size of the networks I
have to deal with. I don't actually think we can do much for that
network Maybe after it gets broken up to different subnets inside of
our network though. Anyway, the question was really about what the
limits of snort are in terms of how much data it can handle assuming we
can get that much data to it. Even with a minimal rule set on a fast
unix box I wonder what we can pull off.
I think other people out there must have run across using snort on
higher speed links (say 600 to 800Mbps) and I wonder what sort of
problems they've encountered and if their solutions might scale up to
even higher speeds.
