Snort Packet Processing issue

[HASSAN Qadeer via Snort-users <snort-users () lists snort org>]

Hello Team,
Hope you are doing great!
I'm using snort version 2.9.12 on Ubuntu 16.04 on vmware with four cores and a single network interface card. I'm 
trying to optimize the performance of network monitoring by running multiple snort instances on different cores.
To generate the traffic, I am using Colasoft packet player in burst mode with a pcap file having 10 million packets.
To test the scenario, I am transmitting 1 million packets to snort and all the four instances of snort are monitoring a 
single interface. The issue is that when i transmit 1 million packets, each core separately process 1 million packets 
resulting in total processing of 4 million packets.
Can you please help me in distributing / load balancing network traffic among multiple cores for snort processing.
Thanks and regards.Hassan Qadeer
