Originally created by @rkkoszewski on GitHub (Jan 21, 2026).
Original GitHub issue: https://github.com/games-on-whales/wolf-den/issues/5

Currently when Wolf-den is idling, it has a constant 3-5% of CPU usage (On a AMD Ryzen AI 9 HX PRO). As long as the wolf-den docker container is running, this never decreases. With "idle" I mean that the wolf-den container is running, but no user has opened the web-panel nor is connected in any other way to the wolf-den server.

This has as effect that a NAS that was idling at around 38w, now idles at around 55w by just having the wolf-den container running (Roughly 17w more of power consumption just to have wolf-den running in the background).

Expected would be to see zero or near zero CPU usage during idle.

Same here, I have the same issue. When checking processes with top, "dotnet" cpu usage is 6%

I am running on AMD Ryzen 7700X 8-core desktop CPU

Does this happen over time, or is this a constant load?

I'll have a look at this when i find the time. Not sure yet what might cause this on idle, but maybe its the dotnetvm optimizing the bytecode. I'll check if maybe an AoT version fixes this.

It is a constant load. Happens pretty much instantly once the container is started.

@Skerga commented on GitHub (Feb 2, 2026):

So after a bit of research i've found some things.

The CPU usage is only high when run inside of docker.
When the server is running outside of docker it idles with ~0.0-0.1% of CPU usage
This might be relevant: https://github.com/dotnet/runtime/issues/73361#issuecomment-1233880643
I'll look into how to and if disabling the Console input might fix the CPU usage.

Yes, indeed I have the same problem which I have noticed... Much heavier stacks still use less percentage of CPU.

Here some example of % Wolf-Den usues compared to other (spoiler it is always the first and i'm not even using it):

Seeing the same thing. Picture from Dockge. Idle should definitely be lower than this.
