Title. I’m rocking the exact same setup as it were on my Raspberry pi 4 (nextdns running on docker, a livestream playing 24/7 on ffplay, ufw, sway, alsa-utils) and the difference is night and day compared to the rpi 4 (temps at 52 degrees versus 74 on my rpi 4 and cpu usage at 0 ~1% on my opi zero 3 versus 6 ~10% on my rpi 4).
