I have two of linuxserver’s desktop docker web apps in a single compose file in a LXC via proxmox: orca slicer, and FreeCAD. Orca slcier would perform just fine, without any issues, but freeCAD doesn’t even have the stream coming up. I had 6 cores and 8GB of ram allocated to the LXC and the encode was like 1.2kb/s and staling out.
I’m running the LXC on a dual Xeon 40 thread haswell V4 system with 64GB of ram. I thought maybe getting it to use the Arc A770 I have in the system would improve performance, or at least let it load, but so far I’ve had no luck. I can get the GPU passed through from proxmox easily, just can’t get the encoding to use it.
No idea if anyone else has had issues with the FreeCAD container on systems without a GPU, but it seems it has some, makeing a GPU for encoding mandatory pretty much.
