Hi @benjamin,
now i can provide you with one specific example. I pressed “Next track” at 01/15 11:14:25.
The playback of the next track startet at 01/15 11:14:40. The time in-between was spend on these related stats calculations.
During these 15 seconds the Roon client is unresponsive. I monitored the Activity Monitor on the Mac Mini and couldn’t see any significant CPU, network rf I/O activities during these 15 seconds. I saw a high number of ports (> 32000) in the Activity Monitor for the Roon Appliance process. After restarting RoonServer everything is back to normal and the port number is 400.
Let me know if you need the complete logfile.
