there is a difference between theoretical academic benchmarks and real
world load - if your workload isn't affected it's pointless

In fact I m just comparing containers, I have no need yet for context
switch, but I hope to understand why nspawn is slower and if there is
something I can do to improve it, for example disabling spectre/meltdown
mitigations improved nspawn a lot, so I was wondering if there is
something else I can do to make nspawn as quick as podman/docker/qemu.

I tested with Export SYSTEMD_SECCOMP=0
no improvement, I still get the same result
thank you,

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
<https://github.com/systemd/systemd/issues/18370>
Do you know why systemd-nspawn is slower? how can I improve it?
thank you
Have you tried completely *disabling* the syscall filtering and
all other seccomp-based features? Export SYSTEMD_SECCOMP=0
before running nspawn and check if it makes any difference...
