[systemd-devel] Why systemd-nspawn is slower than docker, podman and qemu?! how to Improve nspawn performance?

[Badr Elmers]

Hi,
Why nspawn is slow compared to docker podman and even qemu?!
CPU tasks take twice of the time it takes in docker, podman or qemu

here I filled a request to improve nspawn performance which contain the
steps and the full test result:
https://github.com/systemd/systemd/issues/18370

Do you know why systemd-nspawn is slower? how can I improve it?

thank you
badr
