Is this on real hardware? And does “boot” mean to a login prompt? I ask because I’ve never had a computer (no matter how fast) boot in less than 10 seconds on Windows or Linux. Just getting to the boot loader takes a good 3 seconds or more. If I have to FreeBSD to get a fast boot, I’ll do it! (On an old laptop, at least).

That's in Firecracker, time it takes to boot the kernel aka before we start running init. Including userland -- i.e. "boot to login prompt" -- it's around 450 ms on the same VM; I haven't optimized the userland bits all that much yet. Real hardware will take longer and will vary of course; we can't do anything about the time between poweron and when the boot loader starts running, for example.
