I am inspecting two span ports. Each has about 15 million packets per minute, mostly HTTP. Bandwidth is about 2 Gbps on each.
I've noticed one new message on startup with beta version.VLAN disabled, setting cluster type to CLUSTER_FLOW_5_TUPLE
Not sure if this has any effect.

It seems that 2.0.7 work better than 2.1beta3.What's the bandwidth you protect by suricata ? 10Gbps or 20Gbps ?

I have tweaked my configuration to have Suricata 2.0.7 run with minimal packet loss less than 0.01%. This set up does use a ton of RAM 95% of 140GB.As soon as I switch to Suricata 2.1beta3 and run it with the same config, I get 50% packet loss but RAM utilization stays around 50%.
What was changed to have such a big impact?
P.S. I am using PF_RING.
