Roon Core Usage - Hyperthreading

[wklie (Peter Lie)]

@J-in-TO

My question is whether the RoonAppliance is thread based? i.e. It will use 2 cores or 2 threads but not 2 hyperthreaded cores (4 threads).

FYI:

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

The majority of systems used to run Roon have 2 cores / 4 threads or less. NUCs are the typical archetype. We monitor these stats on an ongoing basis to drive these decisions. There is overhead associated to splitting/joining work across cores. It is most efficient to run things on 1 core if they fit there. We enabled the split to 2 cores as a technique for making extreme DSD upsampling cases workable. Unnecessary multi-core processing has other have negative consequences for the overall user…
