@support I’ve been running ROCK with internal storage for close to two years a NUC6i5SYH, but I’ve been growing increasingly frustrated by the sluggish performance and connectivity issues (specifically with iOS controllers). It was lightning fast in the beginning, which makes me wonder whether it is due to my growing library (up from 20k to approx 25k over a two year period), or possibly something altogether different. I am wondering if a clean installation might help. I have core running on internal SSD and audio files running on internal HDD.
I will say that I don’t seem to experience the same sort of issues when using controlling Roon on Mac.
Do you use the Mac on WiFi too or do you have a wired connection to the network for the Mac? Because then it would point to some (WiFi) network issue and reinstalling ROCK wouldn’t bring much.
If it’s OK on Mac then doesn’t sound like a server problem, it would be equally bad if it were. Have you tried deinstall and reinstall of the app on iOS?
