I am pretty sure SMP support has been around in FreeBSD for longer than
that - I think BSD was later. That was one of the reasons we first tried
it out. Had nothing but good results from it in our labs - very
reliable. YMMV, of course.....

We have not managed to test a Gigabit Snort appliance as yet.

Regards,

Bob
