Consistent High CPU Usage on Roon Server without DSP (ref#5IG2O4)

[Jared_Rodeheaver]

What app are you having the slowness issue with?

· Roon

What kind of performance/speed issue are you experiencing?

· The app is using a lot of resources (CPU/RAM)

Please try to reboot your Roon Server

· Yes, rebooting helps, but the issue returns after some time

Please try to reboot your networking gear (Router/Switches/etc.)

· No, the issue is still the same even after a reboot

Is there any change in behavior if you try to navigate to Roon Settings -> Library and set both Background and On-Demand Audio Analysis to Throttled or Off?

· No, the issue is still the same

Does the issue happen on multiple Roon Remotes (controllers) or just one?

· Issue happens on multiple remotes

Router Domain Name System (DNS) change

· I don't know how to do this

What is the operating system of your Roon Server host machine?

· Windows

Timestamp of issue occurrences

· Costant

Describe the issue

I have been having pretty consistent 90+% CPU Usage on my Roon core machine.
I am not running any DSP.

PC Specs:

|OS Name|Microsoft Windows 10 Home|
|Version|10.0.19045 Build 19045|
|Processor|Intel(R) Core™ i5-9400F CPU @ 2.90GHz, 2904 Mhz, 6 Core(s), 6 Logical Processor(s)|
|Installed Physical Memory (RAM)|48.0 GB|
1TB SSD for Roon library ~1150 tracks and Roon backup
Other Sources: Streaming from Qobuz and Internet radio

Any guidance here is much appreciated.

Hi @Jared_Rodeheaver,
Thanks for reaching out to us to ask about this issue. If you quit Roon and then restart it does it immediately start using a high amount of the CPU or does it take some time to reach that level? Also are you seeing any slowdowns in Roon’s performance when this happens?

[Jared_Rodeheaver]

When I restart Roon the CPU usage does go down at last for a while but it doesn’t have a consistent behaviour. Sometimes the CPU usage will spike within minutes of a restart and other times hours later. There is no correlation to performance issues that I can tell. I do have intermittent times when it claims network performance is an issue when using Qobuz but since Qubuz works fine nativity and all network tests are good I think this is some issue with Roon. Let me know if I can provide any other info or logs etc. Thanks!

Attached is the error related to Qobuz

Note this only seems to happen when bluesound nodes are my endpoint.

Hey @Jared_Rodeheaver,

Thanks for the update! Let’s see if refreshing your Roon database has any impact on your performance:

Let’s try a fresh database and see if your issues persist:

• Create a Backup of your current database
• Exit out of Roon + RoonServer (from taskbar area)
• Navigate to your Roon Database Location
• Find the folder that says “Roon Server” and “Roon”
• Rename the “RoonServer” folder to “RoonServer_old” and “Roon” to “Roon_old”
• Reinstall the Roon App from our Downloads Page to generate a new Roon folder
• Verify if the issue persists on a fresh database before restoring the backup

Here is the process outlined from a Windows machine:

Thank You. This seems to have resolved the CPU usage issue.
