openHAB on Raspberry Pi freezes for a couple of minutes

I’m using MySQL which is on another server.
However thanks for your help, this is what I’ll do!

Try zram first. May or may not be sufficient.

It’s really time for a PI with 2gb ram. Most of the time it’s not CPU that’s limiting. I wonder if the Homeassistent guys manage to squeeze python and grafana on a Pi.

That’s a good question, especially since hass.io, if I understand correctly, loads everything in containers which should require even more memory.

I agree, if they produced an RPi with 2gb ram and at least USB 3 I might replace my server with Pis. For most stuff the CPU isn’t the problem, it’s the RAM. And the lack of USB 3 is there only thing holding it back from being a good NAS platform.
