Re: Snort High Memory Usage

2.9.x takes more memory than 2.8.x.  It does much more.  Kinda of a bad comparison.

i thought that was likely the case ;)

what are the numbers under the VIRT and RES columns?

can i assume that you are doing SHIFT-M in top to sort by most memory used?

We had Emerging threats and the original snort rules enabled. Took ET off and
that took the memory down some, but I don't want to sacrifice that if I can
help it.

one box i'm looking at with 2.9.4.1 and only the default VRT rules set with no 
rules commented out or added shows

   VIRT = 371m   RES = 119m

another box with 2.8.6.1 and only the ET set plus some (~15) local.rules with 
some of the ET rules disabled from default shows

   VIRT = 199m   RES = 175m

Currently I’m running 7 snort sensors on my pfsense firewall and each of
them is at 672 mb’s for using memory. Which seems really high. I believe I
read somewhere in documentation that the memory is usually around 200 mb’s.
Can anyone shed some light on this for me?

how many rules do you have enabled?

what tool are you using to view that memory consumption?

what column are those figures listed under in that tool?
