High idle load (fixed in 0.145.6)

[InB4DevOps]

Hey there,

I have this server running on my Synology NAS (DS416play w/ 8GB RAM) and while it runs surprisingly well I'm wondering if you guys are also having a rather high CPU consumption when no one is actually connected to the server?

I'm seeing a constant 33%-40% load for the valheim server process..

Thanks

I can confirm this. I'm running Valheim server on a 2.4 GHz 6 Core Intel Xeon E5-2620 and the Valheim server process is constantly consuming ~130% CPU (i.e. 1.3 Cores).

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
   92 steam     20   0 8966868   1.7g  50140 S 129.3   2.7  28:11.47 valheim_server.

And at the moment nobody is connected to the server.

Only now did I notice this detail. How do you have the server process running as user steam? Is this without using the container?
Mine runs as root.

Look at https://valheim.fandom.com/wiki/Change_Log/Patch_Notes

Seems they have fixed it in the latest update.

Dedicated server CPU usage fix (Framerate limiter)

EDIT: Just installed it and the server load in general is much lower. (both with players connected and idle)

on idle/ no connections after updater did his job.

Yup can confirm

I also have a constant 20-30% CPU load with no players connected.

Is this something the devs are aware of, or did they state wether it could be fixed?
