@bohwaz check the container runtime (usually runc), you can replace it with crun which is faster. Also if you call runc/crun directly instead of using docker/podman it should be faster (there are probably some guides on how to do that online)

@meli Thanks for the pointers! I tried setting crun as the runtime for podman or docker but the performance was similar. Running crun directly is much faster but also more complex: skopeo copy docker://docker.io/alpine:latest oci:alpine umoci unpack --rootless --image alpine:latest bundle cd bundle nc -lU /tmp/my.sock & crun run --detach --console-socket=/tmp/my.sock alpine crun exec alpine alpine true
