Snort 2.6.0RC1 memory usage on FreeBSD

["Richard Bejtlich" <taosecurity () gmail com>]

Hello,

Has anyone else tried Snort 2.6.0RC1 on FreeBSD 6.0?

uname -a
FreeBSD orr.taosecurity.com 6.0-SECURITY FreeBSD 6.0-SECURITY #0: Tue
Apr 18 08:56:09 UTC 2006    
root () builder daemonology net:/usr/obj/usr/src/sys/GENERIC  i386

I've tried compiling it with 3 different variations, namely:

--enable-ipfw --enable-perfprofiling --enable-dynamicplugin
--enable-perfprofiling --enable-dynamicplugin
--enable-dynamicplugin

and then running it like so:

snort -i <interface> -c etc/snort.conf -l .
--dynamic-preprocessor-lib-dir
/usr/local/lib/snort_dynamicpreprocessor

snort.conf is literally the unaltered snort.conf in the distro.  Rules
are the current snapshot.

All three different compilations result in Snort using 183 MB of
memory while running.  This is over twice what Snort 2.4.4 occupies on
the same hardware.  I'd just like to know if this is normal, perhaps
as a result of the dynamic preprocessors?

Does anyone have a different experience?

BTW I tried this on two different i386 systems -- same results.

Thank you,

Richard
