Well, it's a hell of a lot faster now.  :)  Seriously though, the memory
that's being used in Snort 2.0 is in the detection engine.  Make sure
that you are using the mwm search method in the snort.conf (on by
default), that should only consume about 25 - 35 MBs (not counting

If you don't like that, then you'll have to use snort 1.9.1.  We may add
the option in the future for a low memory multi-pattern matcher, but
don't quote me on that.
