Perhaps you should read this comment on the role of hardware in the Roon experience. A large library will affect the performance of the user interface, because the display is built on the fly by querying the database. And with an Intel Atom, I suspect you are going to find the performance too sluggish to be acceptable, even when it is being used just as a Core. You can certainly forget about using the DSP engine in Roon - the Atom will not be up to handling its demands.
Hey @Bernhard_Krusche,
I definitely recommend you check out this post from one of our developers.
Using a Core machine that is below our recommended specifications, particularly with a large library, will likely result in some performance issues. The severity of these performance issues will vary depending on how much analysis is being performed, whether or not you’re using DSP, how many zones you’re streaming to, and the overall size of your library (among other things).
You can certainly let the import process finish up and see if things stabilize, but since that machine is significantly below our recommended specifications, unfortunately performance issues would not be surprising here.
Kind regards,
Dylan
