Didi you see the fast.log and others logs? 

Maybe there are some traffic (icmp or broadcast for example) coming to virtual machine, even little being data, can generated a lot of logs and degree the performance. 

I had a similar situation on a VM of testing. 

Just a shot into darkness rsrs

Assunto: [Oisf-users] Suricata using 35% cpu with no load? 

I've got a random virtual testing machine, and I'm seeing Suricata sitting at about 35% CPU load, even though there's absolutely no traffic heading to it at the moment. Is there an easy way to get Suricata to tell me what it's doing that would cause this? It occurs on real interfaces with low traffic, loopback, as well as bonds where there's no trafic.
