I am new user and just playing with IDS. I have install suricata-2.0.9
without any PF_RING or any other special flags etc.

I am running it on DL360  G8 with 4GB memory. following command i am using
to run on command line.

./suricata -c suricata.yaml -i eth1

on top command it is showing 200% CPU usage without any single rules (if i
load all rules it touch 350% CPU). my traffic rate would be 150mbps
around.  ( I am using standard suricata.yaml config file without any
modification )
