I am planning on moving my Pi-Hole implementation from a RPi 3 to a Rock64 board shortly. I have two Rock64’s, a 4GB and a 2GB. Planning on running Debian Stretch. My current Pi-Hole is also running PiVPN.
Any reason to use the 4GB board for Pi-Hole server? Performance has been OK on the RPi, so I don’t think the extra 2GB will make a difference. Just wanted the opinions of folks more learned than I.
