I think Johann's 1-4s scenario assumes a basic desktop configuration and
a tweaked startup config aimed at such a system. Such a system would not
have two big database engines starting up, but zero. =)

The lowest I've seen on my system, which is quick and has a third-gen
SSD in it, is 8s, but I haven't made any tweaks to startup config at
all.
