Mostly what I mean is that from the time boot has started to getting a
prompt. If you have a laptop, for example, you're booting frequently
and 25 seconds is kind of long. Or, at least, 25 seconds is much
longer than it needs to be. Point is taken, though, and maybe "dog
slow" isn't the right phrase.

At the minimum, things could be vastly sped up by not serializing the
whole operation. Read this article from IBM for an example.
