Multiple Instances of SNORT

[test engineer <test12524 () gmail com>]

Greetings
I'm new to the community and need some guidance.  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.
