Roon: anyone else experience slowdowns after usage?

BTW, I use Roon core on a Linux box with an A10 CPU.  I've never had any of the issues you are describing, so I want to suggest this problem is not wide spread, and a little patience could be helpful.

Do you have a very large music library?

My library is "medium" I guess, compared to many of the Roon forum posters.  About 8000 albums, 4000 local ripped CDs and 4000 combined from Tidal and Qobuz.

Not to be argumentative, but how would being patient help?  I'm not sure what you mean. 

What I was saying regarding my plan is that it's not my practice to disturb the delicate balance that Windows machines represent by updating drivers without a clear reason - just to see if it helps with an application.  So in order to update the drivers, first I need another core I can use if the driver update kills my A10 machine as it did last time I tried it.

@jji666  Do you have NVidia video drivers? If so, Windows OS updates may put the default Windows drivers instead of the third party NVidia drivers. When I ran the app and core on the same Windows 10 machine I had performance issues after a Windows OS update. I noticed that when I minimized the ROON app performance improved dramatically (looking at Performance Manager). So I figured out that it was a video driver issue and ROON a developer confirmed the NVidia driver issue.

Due to this video issue on OS updates I separated the full app to a CORE and APP on 2 machines. The separation is actually a rather difficult process and you need to follow the steps properly so as not to mess up you ROON setup.

My ROON server is not that powerful and also electrically noisy (ROON  says that is fine). I am a super user of ROON with 3 zones streaming at the same time with 2 of the zones using CONVOLUTION filters. My weakish CORE server has no problems. 

I also use fibre optic cables to kill the noise on my network before it goes into my DACs.
