Description Of Issue
Even when idle, the Roon instance on the iMac uses 280% CPU. This is especially strange as the core is on a NAS, so the iMac Roon app should just be idling. Picture shows Activity Monitor history starting with Roon playing internet radio, then shutting down the app for a few seconds and then restarting. Restarting jumps CPU usage immediately, even though nothing is playing.
If it helps, I previously used the iMac as a Roon Core, but then installed the core on the NAS and now the iMac acts as a controller/player.
