Docker is a Linux thing (cgroups, overlay fs etc). On Mac and Windows it's emulated using Linux VMs and of course it thus runs like crap on older hardware. Just keep using Linux if you need Docker or Podman. There's also a proof of concept implementation of OCI on FreeBSD called runj, but it's incomplete due to the fact that OCI relies on Linuxisms.
