Running multiple Snort instances without a method of packet distribution / load balancing will not achieve what you are after. Your best choice would be PF_RING.

I have a Dell R720 with plenty of memory, CPUs and storage. I'm using an Emulex DAG NIC. Running minimal install of CentOS 6.5 with Snort 2.9. My CPU usage hits 80% with only 500M of traffic and Snort starts dropping packets. From what I've read, I can spin up more instances of Snort on the same interface and perhaps specify different CPUs for each process. I start Snort as a daemon via command line for now using: /usr/sbin/snort -G 1 -A fast -U -b -d -D -i dag0:0 -e -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort I tried spinning up another process with -G 2 but no new processes start when checking ps -ef | grep snort. Any direction is greatly appreciated.
