John Porpora commented on GUACAMOLE-1494:
-----------------------------------------

alright, updated to matching kernels, added some more cpu tags. Reinstalled 
ubuntu and docker. Reinstalled guacamole's docker config. Changed from sata to 
virtio. 

issue remains. 

I'm at a total loss. Seriously considering just getting an intel build. My xeon 
E5-2667 v2 is outperforming the Ryzen at this point. 

Are you using Proxmox by chance?

> I'm trying to migrate my vm's from a Intel Core i7-4790S system to a AMD 
> Ryzen 9 5950X one and am unable to due to a massive performance loss when on 
> Ryzen.
> Is anybody else running this on AMD? 
> I've tried both LXC Container and a Docker Container hosted on a Ubuntu VM, 
> same issue, as soon as I'm on the Ryzen build, performance is abysmal and CPU 
> usage spikes to 100%. 
> Everything else on the new system has performed well, except this. I'm out of 
> ideas. Is there a missing instruction set or something?
