OK, at this point I’d like to clarify for myself is this a question or support request.
If it is the former, the answer would be: “I don’t know, because it depends on many aspects: library size, hardware of the machine where Roon Core is installed, network setup and channel bandwidth, your usage pattern.”
If it is the latter, I need more info to clarify your situation, you can use this FAQ as a guide to provide us more details.
Thanks
