I've 2 routers at home RB750Gr3 and C53UiG+5HPaxD2HPaxD (hap ax3) and here is the memory usage I've right now, my ax3 is brand new nothing installed, RB750Gr3 already has some small firewall rules 2 wireguard tunnels and an address list with 926 entries:
RB750Gr3, 195.5MB of 256MB -> ~24% usage.
C53UiG+5HPaxD2HPaxD, 682.8MB of 1024GB -> ~33% usage.
Is there an explanation for that? how can I check what is eating the memory? remember my hap ax3 is brand new.
