On my desktop I can restart X (everything cached in RAM that is) in <
1s. Of course if a fresh start takes much more time, it can mean it is
reading a lot from disk and there would be room for real startup
performance improvements. But at least it's not spending 10s probing
video outputs etc like a few years ago.

It's a bit of a blame game also, why try to cut .5s in X when gnome
takes 30s, we can say. One Gnome developer would say why try to cut 1s
in my module when the other modules take 28s. And so on.

I remember seeing some recent Gnome analysis, some kind of blog in
three parts. It was linked from planet.ubuntu.com I think (which
unfortunately does not have a backlog and can not be searched). I can
only find this old stuff now:


I am crossposting this to the almost-secret ubuntu-boot ML, which has
way too little activity :) Maybe getting the community more involved
would be worthwhile. There is the spec page
https://wiki.ubuntu.com/FoundationsTeam/Specs/BootPerformance and some
older wiki pages like https://wiki.ubuntu.com/FasterBootProcess but
maybe something more inclined to discussion and suggestions could be
created. What about a forum where people can suggest things to improve
and developers can post things to test? Or should ubuntu-boot be used
for this?
