[Oisf-users] Optimal Performance for Netmap IPS

We have netmap running inline successfully. However after about 10 seconds suricata stops passing traffics between the interfaces in IPS mode (em2-em3)

current config:

Suricata 3.1.1 release

Freebsd 10.3

8 core / 16GB memory / 512GB SSD

Can anyone recommend optimal performance settings for stream etc? We tested the same config with snort/netmap without issue except snort appeared to limit our bandwidth heavily.

Any advice greatly appreciated.
