I currently run Hassio on a RPi 3 and the performance is adequate except for updates, which are occasionally problematic.
There are a few posts about Hassio here, but they’re quite old. I’ve also done a web search for running Hassio in an LXC with a few results that weren’t entirely satisfactory.
Has anyone here run Hassio on the Omnia. If so, what kind of performance did you get? Did you follow a guide? Was it better than running it on a RPi 3?
 I found this on the Debian site:
which specifically references the Turris Omnia, go figure.
