Just to pile on, I’ve been really disappointed with how sluggish that Roon has been since sometime around the launch of ARC. My library is 95K tracks on a Nucleus+ (upgraded to a 980 Pro SSD and 32GB RAM), most of the content is on an internal SSD, and some on Qobuz and Tidal. My main issue is searching and filtering on tracks (see support topic I submitted this week below). And I also have sluggishness when I select an album to play - it can take 30 seconds or more to start playing.
I’d love to see Roon focus more on performance and optimization rather than introducing more new features.
