Hi @mzbe – thanks for the report and sorry for the trouble here.
We’ve tested Roon with some very large libraries, and depending on system specs, we’ve seen it stable (if a bit slower than we’d like) on Windows with over 300,000 tracks. Mac isn’t able to handle quite as many, but you’re correct that memory issues are likely at the collection sizes you’re talking about.
I would be interested to know how many tracks you’re importing here, but regardless I can tell you that until we move to 64 bit builds, performance with 30k albums imported is going to leave something to be desired.
@DrTone is right that our upcoming headless builds should help, and those are coming soon (most likely in the next few weeks). I will definitely be interested to see how they perform for you.
As for moving to 64 bit builds, that’s absolutely going to happen and I think you’ll be in much better shape once it does. However, moving to 64 bit will likely require a few weeks of development, followed by a few weeks of testing. So, the work will happen, but the question is when.
We’ve heard from just a handful of users having issues with collections this big, and we’ve talked with all of them, to explain the issue and make it right. You’ll be hearing from me as well, and we can decide how you want to proceed. Like I said, this remains a priority for us and it will happen, but the small number of affected users has pushed this just a few slots down the list of priorities, and I want to be clear that it’s hard right now to give you a more firm timeline.
I’ll be in touch via PM @mzbe and we can figure out what’s next. Thanks for the question, and for your patience!
