Hi @Haioken,
I’ve personally never had the chance to try the Tumbleweed flavor on real hardware (only VMs), but never noticed slowness… Maybe it’s because I haven’t had the chance to use it on a “full-fledged” system with substantial pool(s) and share(s).
You did mention you had a hard time installing it, however, so maybe there’s something there. I usually simply follow the dev notes–and you did mention you would do that as well–but would you remember what the difficulties were? From the top of my head, I believe these notes are up-to-date and to get TW up and running but I may forget something…
I’m sorry I can’t provide a clear help for now
