My Podman starts containers in arch x86-64-v3 with rosetta on for 27 seconds which Docker does it in 9s. I wonder what's wrong. I've already upgraded Mac to Tahoe (which has x86-64-v3 support included into rosetta)

There is definitely something wrong with your setup. I can run an amd64 container on my Macbook Pro M3 in well under a second:

    [~]$ podman pull --arch=amd64 debian:13
    Resolved "debian" as an alias (/etc/containers/registries.conf.d/000-shortnames.conf)

I've checked and there is no difference between podman and docker on my machine.

However when running a spring boot over eclipse-temurin:25-jdk-ubi10-minimal image there is this huge difference

  podman run   0.02s user 0.01s system 0% cpu 24.960 total

you can see the java app starting slowly. I've double checked that rosetta is enabled on podman.

  % podman machine inspect podman-machine-default
  ...

        "Rootful": true,
        "Rosetta": true
     }

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... :)

[p0w3n3d]

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)

[cdrage]

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)

[p0w3n3d]

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.

[p0w3n3d]

are you by any chance one of those Claw raging robots? really? created an issue?

[worthless-trash]

Pretty sure this guy works in that project.
