My question is wether "8x faster than docker" means that containers run faster or that the tooling around them runs faster

Expecially considering that pretty much every post-Docker container tech is "faster" than Docker. Docker is a pretty low bar these days IMO, it would've been better how Kiri compares to actual performant container runtimes like Podman, systemd-nspawn, incus etc.

And for macOS, the comparison should be done against Apple containers, OrbStack, Colima etc.
