FreeBSD can now boot in 25 milliseconds

Current FreeBSD 14.0 Boot time in ~25ms is middle of the pack, and still has some catching up-to do.

In the race to accept incoming SSH connections, the clear winner — no pun intended — is Intel's Clear Linux, which boots to a running sshd in a blistering 1.23 seconds after the instance enters the "running" state. After Clear Linux is a roughly three way tie between Amazon Linux, Debian, and Ubuntu — and it's good to see that Ubuntu's boot performance has improved over the years, dropping from 18 seconds in 16.04 LTS to 15 seconds in 18.04 LTS and then to 12 seconds with 20.04 LTS. After the Amazon Linux / Debian / Ubuntu cluster comes SUSE Linux and FreeBSD; here, interestingly, SUSE 12 is faster than SUSE 15, while FreeBSD 12.2 and 13.0 (the most recent two releases) are noticeably faster than older FreeBSD.
