I restarted my computer as I often do when Roon bogs down and runs a bit slowly. However, this time when Roon starts up it loads very slowly, Qobuz doesn’t work, and there is a lag with all of the controls of close to a minute (press play, 1 min loading time; press pause, 1 minute delay). I check it with Tidal and it does the same. Even my home library on the external HD is slow, although a bit quicker. I clear the cache, shut down all other programs, check Activity Monitor, and nothing else is running except the Mac program that manages heat and throttles the processing. I shut the computer down to cool it, restarted it after about 30 minutes and the process repeats.
I have not done anything recently that is taxing for the Mac. In fact, all I did new was delete the Mac’s cache to help speed things up. I’ve shut off Spotlight and other processing hogs, and Activity Monitor says not much is using processing/memory/network time except Roon. But it continues to be very slow. Other apps run quickly and normally, such as Qobuz and Tidal’s native apps, iTunes, and Chrome.
What is going on here and what can I do to speed Roon up. This is not an old Mac Mini and it has a fast processor and plenty of memory to do this.
