Recommendation for a large library

[Larry_Post]

I’ve run my much smaller library (10k albums and 100k tracks) on Windows 10, ROCK and Ubuntu. Not directly comparable but the technologies used on Windows and maybe? ROCK allow better performance, namely .NET vs. Mono that is used with Linux and MacOS. Windows is hands down far more responsive (for me) than ROCK or Ubuntu all with the same library running on the same hardware i7-6700, 16GB, SSD (sata) for OS. I would just swap boot devices to compare easily.

Roon Server running very slowly

Although Mono does perform well, many components (most notably the GC) on the Microsoft .NET perform much better. This gap is shrinking since Xamarin was acquired by Microsoft but it is not the same still. Our customers with 300k+ tracks are pretty much required to use Windows right now.

You could try a virtual Windows instance on your Mac as a test. No need to activate/license Windows just to host RoonServer. You won’t be able to customize some things but none that really matter to the use.
