Severe latency issues affecting Roon performance on high-end system (ref#CGK4Q4)

What’s happening?

· I'm noticing slowness when using the Roon App or Roon ARC

Describe the issue

The lag on selecting a song, an album, anything is ridiculously slow.

My system is high end and it is embarrassingly let down by the Roon software.

I have ultra fast FTTP and speeds on other apps are normal.

This is seriously spoiling my musical enjoyment. I would like a walk through to troubleshoot. I don’t want to be blinded by technicalities.

I have recently upgraded components so the issue does not sit with the hardware.

Streaming wise I use Innuos Statement through Innuos Phoenix Net and high end Ethernet cabling. The speed of the components is not the issue

I have had this latency issue for some time but it’s getting worse

Please help

Describe your network setup

Router Netgear Orbi, RBR850, wifi 6, firmware version v7.2.6.31
Innuos Phoenix Net
Ethernet from Orbi to Innuous Phoenix Net
Ethernet from that to Innuos Statement

Hello @Richard_Pratt ,

Please keep in mind that Innuos products are underpowered and do not meet the minimum specifications to work properly with Roon, they have this as a note on their website towards the bottom here:

Innuos Servers hardware specifications do not meet recommendations provided by Roon – you can check them here – especially with regards to CPU.

With that said, if you can please let us know the exact local time + date + tack when you next observe this behavior, we can look into diagnostics to see if there’s anything else that jumps out, or if this is a general performance issue due to the hardware.

Hi Noris. Thanks for your speedy feedback. I will put the hifi on this evening and note the time etc. I cannot believe such a high-end product as the Statement would have such lag. I am hopeful there is another reason that can address the problem

Hi Noris.

I am in touch with Innuos separately. 50% of their users use Roon interface so I don’t think that’s the problem.

It could be a networking issue, although I do have FTTP.

I used Roon last night from approx 7 30 to 10.00pm and experienced the same latency challenges

It would be good if you could run some diagnostics.

The Innuos view is that the Statement is more than up to the job of meeting the required standards.

More than happy to have a call on this matter to avoid the inevitable to/fro of emails

Hey @Richard_Pratt,

We were able to review a fresh diagnostic report of your Roon Server machine and see some errors in relation to your local library. As a next step could you:

  1. Temporarily disable your local library, and only rely on streaming content from Tidal - and let us know how performance feels.

Thank you! :raised_hands:

Hi Benjamin. How do I do that?

Fyi, I have currently disabled Roon and am using Innuos Sense to play music and there is zero lag. Instant response to selections

That seems to rule out networking issues

When you say some time, how long?

I use a Innuos Zen mini mk1 (10 years old?) and it’s been pretty bullet proof as a server running Roon.

In the past few weeks however there’s been a lot of hanging, skipping tracks mid way through and losing of the list of audio outputs mid song. I’m sure it’s totally unconnected to the release of the new Nucleus but it is pushing me in that direction…

Hi Nadeem. Not sure exactly but longer than a few weeks.

Roon RAAT protocol has minimal buffering other services buffer much more so stuttering and dropouts are less. So it does not rule out network, indeed in indicates network deficiencies,

Hi @Richard_Pratt

You can disable your local library by going to Roon settings → Storage and clicking the three dot menu next to your watched folder(s) and clicking disable in the menu.

Then go to Roon settings → Library and click “Clean Up Library”. In the menu that pops up check the box next to “Clean up x files that are Associated with disabled Storage locations” and click “Clean Up Library”


Once you have completed testing you can easily restore your library by clicking “Enable” in the same menu where you found disabled.

Thank you. I have done that this morning

Fyi. I mentioned the other day that I started using Innuos Sense the other day without any issues. I reverted to using Innuos as the Roon Core the day after and the latency issues had improved dramatically (before library clean up)

You can look at performance maybe. I used the system around 4.30pm yesterday until about 6pm

Hoping that off / on routine coupled with the library clean up will lead to sustainable improvements

Hi @Richard_Pratt,
Since your above comment have you had any latency issues?

Yes unfortunately

Hi @Richard_Pratt ,

Looking over your Statement logs, it looks like there is a lot of analysis going on still. I suggest trying to disable or throttle background and on-demand analysis to see if it helps:

Hi yes the app is still temperamental. I have someone coming to look at it on Friday so will try this then.

Sounds good @Richard_Pratt let us know how things go :+1:

Hi Benjamin. I’m afraid it’s not a great news story. This pm I played Roon and it performed ok. This evening the 30 sec + lags for any action resumed

I switched from Roon to Innuos Standalone and the response times for music selection are fast / instant

Hi @Richard_Pratt,

Thanks for letting us know!

At this point, we believe this performance issue is likely due to not meeting the minimum specifications to work properly with Roon.

I apologize that we’re not able to offer any additional suggestions at this time. :-1:
