Poor DSD512 upsampling performance on NUC10I7

[GregD (Greg Dowling)]

My guess was correct, it uses 2. This sort of parallelisation isn’t easy to do!

DSD512 - Is this even possible? [yes, just needs more cpu]

Roon uses 1 core per zone normally, or 2 if you enable “parallelize sigma delta modulator” setting and are doing DSD output. If you haven’t turned this on yet, try that first: [20 PM] In general, the “many slow cores” model like your XEON is not the best for Roon. Almost none of our users have this class of hardware, so putting in a ton of effort/complexity optimizing for horizontal scalability doesn’t make a lot of sense. This isn’t just about audio, either–for UI responsiveness it’s also adv…
