Increased CPU usage from CrowdSec after updating to OPNsense 26.7

[josephistired]

After updating my firewall to OPNsense 26.7, I've noticed that the CrowdSec plugin appears to be using significantly more CPU (upwards of 100%) than it did before the update.

Has anyone else experienced this after upgrading, or is this a known issue with 26.7?

For reference, here's some information about my system:

OPNsense version:

OPNsense 26.7 (amd64)

I use the same version of CrowdSec and it still works the same as in 26.1... I don't have any more CPU usage. I think since I updated to 26.7 I have less CPU usage overall. It works very, very well. 👌
