Is this still OK?
I am running firmware 3.207, I have AdGuard Home enabled with 50k filters and also
clients real-time speed and traffic statistics enabled.
htop shows the below info, hope this can be useful.
In addition see the output of the command I found in the other post:
pid=$(pidof AdGuardHome);cat /proc/$pid/status
and then running the command:
echo '3' > /proc/sys/vm/drop_caches
memory drops down to 61%.
