In test environment (not real traffic, just stress test and pcaps
replications using tomahaw and tcpreplay) I got better performance in
througput running with 4 queues. This is not the case because the max
throughput in this network is 25 Mbps and running with 1 queue should be
enough. I used 2 queues just for testing. I don't believe Suricata would
process more than 500 Mbps of througput running with 1 queue. I 'd rather
avoid running multiple instances.
