Matthas:
I worked through some of the examples of the settings described in the Suricata forum discussion. If my observations is correct, the issue centers around the flow manager. A change to it has made a big difference it the resource usage by this process. Its likely going to come down to live with the load created the v6 version or revert to v5 and wait for them to get to the bottom of this. No combination of settings in the flow section of suricata.yaml ever seemed to reduce it and instead increased it.
I don't use low power systems for IPFire and dont have access to one but others with these systems may want to take a look at their performance numbers and report back as to whether they can live with the higher load.
Best regards, Fred

Hi,
looks as if there is something going on in the suricata forum regarding cpu load:
=> https://forum.suricata.io/t/cpu-usage-of-version-6-0-0/706
I can't really interpret the numrous screenshots and ongoing discussions, but could it be that this is related to what I'm experiencing when upgrading from 5.0.x to 6.0.x?
Best, Matthias
