Audirvana optimizes the OS, Roon doesn't. MacOS is a nightmare to tune, there's so many processes active you can't get rid of. Many people switch to Linux or Windows (like Server 2012 or W10 with Audiophile Optimizer to take care of the the tuning process) for lower footprint.
Adding an extra network connected renderer like the SOTM SMS-200 or microRendu in addition to the PC is even better since that is even more lightweight and it uses optimized hardware. Unfortunately the server hard- and software configuration and network topology design upstream of the network renderer still matter. It'll easily beat the Mac on its own though (with or without Audirvana) and best of it all one can keep using the excellent Roon.
Edit: not sure if I made my point which is: don't blame Roon but your non audio dedicated computer running a over bloated OS!
But I agree, it's very off topic, sorry I added to it!
