[Bro] Bro performance issues

[Tomer Teller]

Seth, here is my configuration:
 
Bro 2.0beta
Running on Debian GNU/Linux 6.0
 
broctl config | grep pfring
> pfringclusterid = 21
 
ldd bro

for i in  $(pidof bro); do echo -n "Pid:$i " ; cat /proc/$i/environ | grep -w 'PCAP_PF_RING_CLUSTER_ID';  done
 
Shows me that all instances exported the PCAP_PF_RING_CLUSTER_ID (also tested PCAP_PF_RING_USE_CLUSTER_PER_FLOW)
 
Again, Traffic does not split between the workers, they see the same packets.
