Mostly boot time.
https://systemd.io/OPTIMIZATIONS/
"System can offer boot times of less than 3s
That's the same as if I said "Cyberpunk 2077 can offer 240 FPS in native 4K". Sure, but only on a professional PC with many GPUs.
Not really. The optimizations arent rocket science and distros implement them already.
Then why do I not have 3s boot time? That's my point. It depends on the hardware.
You dont have it with any systems because youre running grub most likely. Systemd boot can skip that entire process and start everything up in parallel.
Use systemd-analyze blame to see what's making your boottime take so long. Its likely spending ages trying to mount a drive or something.
