I am new to RPI and Hifiberry OS...
I connected my music library on my Synology NAS. I have several 10 000s songs. As it was going through the library it rendered RPI mostly unresponsive - I could not get to hifiberry.local most of the time. I would think it would run in the background.
I have RPI 4B with 2GB of RAM connected via Gbit Ethernet, hifiberryos-20201213-pi4
