For the most part I’ve done alias docker=“podman” and it’s been fine. Been running multiple instances of haproxy in rootless pods oh rhel8 for over a year, it’s been unstoppable.

I also use it on my workstation as the backend for distrobox. The machine is a Ryzen 9 3900X with 64GB of DDR4-3200, always running at least two VMs. Very little resource impact with both Distroboxes running (one with GUI, one without).

Anecdotal, so also not particularly strong evidence either, but probably better than a load of marketing wank.
