Description
Issue Description
podman version:
Client: Podman Engine
Version: 5.2.5
API Version: 5.2.5
Go Version: go1.23.2
Built: Fri Oct 18 02:00:00 2024
OS/Arch: linux/amd64
When pulling a large image, podman allocates memory seemingly equal to image size. For a 13G quay.io/fedora-ostree-desktops/kinoite:41
podman allocated ~13G of memory.
Steps to reproduce the issue
Steps to reproduce the issue (with rootless podman)
- podman pull quay.io/fedora-ostree-desktops/kinoite:41
I can't reproduce this with rootful podman, that only floats around 100M.
Describe the results you received
Memory usage scaling with image size.
Describe the results you expected
Memory usage being more or less constant.
