Ahhh, one of the reasons could be that Docker Desktop by default uses 50% of your RAM when they create their VM and the maximum amount of CPUs.

Podman Desktop by default has a much lower RAM (4GB) + CPU usage (50% CPU). That's something that could be improved... I've opened up an issue: https://github.com/podman-desktop/podman-desktop/issues/1634... :)

No I checked it against the amount of RAM. Podman with 8GB does not increase speed, Docker with 4GB is still 9s

  podman run   27->24
  docker run   9.4->9.769 total
(I increased limit in podman and decreased limit in docker). This happens with amd64 arch images (which I for some reason need in my work and cannot rebuild)
now I'm curious why it's still slow even with the increase of ram + cpu, I'll sync up with the podman core team why it's benchmarking much faster in docker vs podman (assuming both are using rosetta 2 on your machine)
I have double checked if my rosetta is enabled. I also requrested using "apple virtualization" instead of libkrun

Because podman doesn't work as well as docker.

are you by any chance one of those Claw raging robots? really? created an issue?
Pretty sure this guy works in that project.
