USB connection from Rock to DAC. Streaming from Qobuz and local NAS library
Number of Tracks in Library
190k tracks and 13,4K albums
Description of Issue
Roon is very slow (10-20 seconds to start playback). I used to have this issue few months back. I then decided to upgrage RAM to 64 Gb, which solved it at the time. But now I have the same issue. My network speed is superb 500 Mbit for outside and 1K megabit inside the house.
I noticed that the issue re-appeared this time after using backed-up library after electricity failure.
I am also finding Roon very slow these days but if I reboot the server then it runs much faster⦠for a few or several days but then it starts to slow down again with big pauses in the UI on Android phone or Apple iPad devices.
Checking memory usage at the server it does LOOK like there might be some sort of memory leak going on.
After a reboot RoonAppliance is using around 800MB of RAM but over the next several days that starts to creep up. A week later it is typically using nearly 3GB of memory.
As a software developer, I have to say that seems a bit much.
So currently I find myself having to reboot the server every few days in order to keep performance acceptable.
Anything else I should try to investigate this further?
Thanks
Roon Server Machine
Intel NUC i5-6260U. 8GB RAM. 256GB SSD
Windows 10 Pro x64. 22H2 Installed 18/08/2021 OS build 19045.4046
Running Windows Server client (for backups) but nothing else.
Windows defender antivirus and windows firewall are both OFF.
Networking Gear & Setup Details
1Gb ethernet to TP-Link network switch to router.
Library is on a Synology DS918+ NAS on the same 1Gb network switch.
NAS has 16GB RAM with a 7TB RAID6 in 4x3.6TB
Network only very lightly loaded. Not a lot else going on.
Connected Audio Devices
NONE.
Multiple playback zones around the house are mostly Pi DACs (Allo BOSS, BOSS2, the odd HiFiBerry) plus a couple of airplay devices.
I do use multiple zones most days and I switch UI between PC and Android and Apple devices and I do sometimes/often transfer audio from one zone to another.
Number of Tracks in Local Library
The bulk of it is in a single NAS volume that is 8544 files in 761 folders.
Around 199GB altogether.
I have a couple of other smaller volumes on that NAS and one windows server for podcasts etc.
Services
Tidal and Quobuz
I sometimes find the Qobuz service makes things a bit unstable (big pauses in waiting for search results or playback) and when that happens I disable the Qobuz service which seems to help a bit but when memory consumption approaches 3GB disabling Quobuz does not make much difference.
There is a potential fix that is live over on our early-release build. We should be pushing this through as an update later this week. Keep your eyes out for an update, and let me know how things perform afterwards.
It was not resolved right after the update, but few days later it now works at a blink of an eye. And I do have a BIG library of 192K tracks. It just fly as a rocket! Thanks
Roon UI on Android phone still painfully slow here
And itβs only been running a few days but server memory use has grown from 800MB to 3.5GB.
Surely that canβt be right? Where is all that memory going?
