parallel if nothing is changed. And this is from cold caches.
Which is probably about the same time as '''one process''' for the old
docbuilder.

Sure.

I doubt it. My timings suggest that some documents need 2 ~ 3 seconds to
build, which is pretty close to the Sage startup time. So I think there is
a substantial gain there.
I think the elephant in the room is still: why did we care so much about
speeding up the ''initial'' build of the documentation (#6495) at the
expense of ''rebuilds'' of the documentation? When doing a few rebuilds of
the documentation, you lose all the time which is gained by #6495.
