Slow read from attached volume - Is there a way to speed this up?

[m-schenker]

Hi there dear developers and community,

I struggle with a problem in regards to volumes. I am trying to run Ollama and other LLM related tasks in podman containers. I have a mdadm raid-0 based array, formatted with XFS, that my computer can access with up to 12GB/s sequentially with a single process or up to 24GB/s sequentially with two or more processes to load large files from. Unfortunately it seems Ollama and other containers struggle to load files from this array when used as a volume and seem limited to loading files with 1-2GB/s at the maximum.

Is there any way, any trick, to speed this up or is running these workloads in podman simply the wrong solution?

Thank you.
