When I got to about 65,000 tracks in the library (maybe three months ago?), Roon slowed down in the following way. When shuffling through all the tracks, I like to build a playlist by using the thumbs up or down until I have one or two hours of music lined up. The time it takes from clicking either thumb to Roon displaying the next track to thumbs up or down increased. Now it takes about 2-3 seconds after I click the thumbs down, and about 3-5 seconds when I click the thumbs up. That goes up to about 10 seconds, if I skip the currently playing song while Roon is “thinking” of which song to suggest next (during those 2-5 seconds after clicking the thumb).
This delay doesn’t seem to have developed gradually. I am under the impression that it went from a delay of about half a second to what it is now very quickly. As such, I have the nagging suspicion that an update to the software might have done it. However, the size of the collection and the hardware running Roon seems to be the more likely cause.
The hardware in play is as follows: NUC5i3RYK with 8GB of RAM and SAMSUNG 850 EVO M.2 2280 250GB SATA III 3D NAND Internal SSD running ROCK and not storing any music; Synology DS211j NAS storing the music (all FLAC); Android tablet as Roon remote; Squeezebox Touch endpoint; separate DAC connected via coaxial SPDIF. I would blame the NAS, but it’s at about 50% capacity on a striped pair of good quality spinning drives. Everything is connected via gigabit ethernet, except the remote control, and the delay is there even if I use my ethernet-connected desktop as a remote.
The NUC also does volume normalization, and I upsample everything to 24 bit 192/176 (I use the “multiples” option).
Is the NUC just too wimpy for that many tracks? Would it help if I connected the NAS to the NUC via USB? I suppose it could also be an update to the Synology software (those come along frequently).
Is there something I can do to the NUC to light a fire under its ass (like overclocking)?
Thanks for any help you might offer.
