My experiences with Rock and a 500k+ tracks library

Library scanning not using all AMD Ryzen CPU cores

Something major has changed since that thread. We stopped using mono for Roon OS (ROCK / Nucleus / Nucleus +), so the performance gap with Windows no longer exists. At this point, for a large library, I would probably lean towards Roon OS. I would reiterate the recommendation to use local storage for the content, and get the fastest NUC you can, with plenty of RAM.
