Roon 2.65 - it was faster for a while, not so much after a while

I always try to use the latest versions of the software I use and update it promptly. In early April, I built a server on a NUC7i3 with 16GB of RAM, installed the latest version of Roon Rock 2.1 with server 2.64 (or 2.63 at the time), and this problem persisted from day one. Then Qobuz changed its CDN, which also led to some known issues.
Prior to this, the server was deployed on Sinology Nas, and I can’t say whether the same problem existed then, as Nas would automatically go to sleep at night and wake up in the morning, meaning it rebooted every night, and I didn’t encounter this problem.

Yes, I have created a support ticket a few days ago:
