After using Roon for several years, on a lifetime purchase, I am giving up on this interesting/promising but rather unprofessional project. It has been really slow for a prolonged period, but in recent weeks it is almost unresponsive and completely useless. I have about 110k albums and 230k tracks, used to run it on a ROCK on a NUC8i7 with 32GB RAM but now tried to switch to a MacMini M2 Pro with 16GB RAM to no help. I am now switching to some other program; considering Audirvana or some of the RaspberryPi players, but any suggestion is very welcome!
PS! I should add that I have posted several posts over the years on the problems I have experienced but never got any response from Roon. And, that is the support they offer for a 700 Euro product.
