I have a library of ca. 38k songs + Tidal.
I run Roon Core on a Synology DS918+ NAS, with 8 GBs of RAM and an Intel Celeron J3455.
The files are on the NAS (5400-rpm spinning disks) and the Roon database is on a Samsung SSD drive connected to the NAS via USB.
Even playing around with the equaliser settings, the CPU usage on the NAS rarely goes above 10% when playing music; sometimes it may peak at 18-20% when searching the library, but I wouldn’t say Roon has ever been slow.
So my question is: when is a Celeron not enough? When do you really need an i3 or i7 processor?
Is it when you have, I don’t know, 6 zones playing together, all with different EQ settings? When you have a library much larger than mine?
Or would an i3 or i7 CPU mean much faster searches but not make a difference when playing music?
