> In the 1990s System 7 would start in a few seconds from hard disk on a Mac SE/30.

A fresh System 7 install on an SE/30 would boot from a hard drive in ~20 seconds. Adding system extensions could double this pretty easily.

On a not so fresh install it boots in 13 seconds here : https://www.youtube.com/watch?v=LgltFQss3yU Pretty sure mine would boot even faster
