Hi,
I am completely new to firewalls and OPNsense. I switched from my previous Unify installation to a N6005. I installed Proxmox and virtualised OPNsense on it. Currently installed is OPNsense 22.7.7_1-amd64, working with the default configuration + IPS/IDS.
Unfortunately, my ping has periodic lag spikes:

Do you have any idea which settings could affect this? What information can I provide so you can diagnose my problem easier?
Kind regards,
Jakob
Hi,
How often do you see latency spikes ? There is no time unit indication on the graph you supplied. Also, how many firewall aliases do you have ?
We run many virtualized OPNsense instances on Proxmox too and had to deal with minutely CPU spikes.

Hope it helps,

Hi, thank you very much for your reply.
The timespan of the graph were 98 seconds.
I solved my issue yesterday by switching from Linux network bridges to PCI via IO_MMU. Now everything is working fine and the spikes are gone.
Kind regards,
Jakob
