I’m now running Roon 2.65, and even during real-time DSD-to-PCM transcoding the system remains extremely stable. CPU usage stays low (around 15% average), I/O wait is basically zero, and memory usage is completely under control.
Honestly, Docker on QNAP performs noticeably better than the native QNAP package ever did: faster library scans, quicker searches, and much better overall responsiveness, even with a large library of about 5200 albums and roughly 11 TB of music.
At this point, for me, it is clearly the best solution.
