what is the advantage of having a Roon core that's not on your computer?

I currently am using my iMac as my Roon core.  It feeds an Sonore urendu downstairs and an Node 2i unpstairs.  Is there a SQ advantage in getting a separate computer such as a NUC, a Roon nucleus or a Sonictransporter from small green computer?  Is it a speed issue or CPU power issue?  I do notice with very high res files (196k 24bit), my stream sometimes can't load, especially if all my web browsers are open on my computer.  Is my internet too slow or is Roon running poorly on the Mac?

thanks

Hey,

Roon core is CPU intensive, but that's relative.  If you don't use any DSP, especially upsampling to DSD, or convolution filters it doesn't need that much CPU power.  It may also compete for RAM, which browser pages can really eat up, which competes with Roon. If you run out of RAM, you end up doing a lot of paging out to and from disk, and that brings the performance of everything to a crawl.

Putting your Roon core on a dedicated NUC means you won't be making it compete for resources on your iMAC.
