Is anybody else seeing this? I had to disable and uninstall it, or there was a huge performance hit.
I was seeing something between 40 and 80% CPU usage from it in System->Diagnostics->Activity.
Then my download rate was only about 55Mbps, whereas if I disabled maltrail and rebooted, it went
back up to about 320Mbps.
I did find this forum message for OPNsense 19.7: https://forum.opnsense.org/index.php?topic=14021.msg64454#msg64454 (https://forum.opnsense.org/index.php?topic=14021.msg64454#msg64454)
It is likely that my installation was not correct, since I didn't really know what I was doing. The sensor and the server are on the same machine, so most of the setting seemed to be the default ones.
I reinstalled, and read up more on the software. The new installation ran smoothly for about two months, but today went back to high CPU. Apparently, no one else sees this?
