@Don_Faust What exactly is your cpu model and are you using ssd? 330k tracks is a lot and will take a few mins to load even on an i7-7700. Browsing is where you need the speed…loading will be slower if your not using an ssd for your OS. The nas is not the issue normally when performance is slow unless you are running the core on the nas.
I run my core 24/7 so don’t shut it down…that helps a lot won’t improve your remote use tho…that’s just your core running out of puff
