Hi Pascual,

whenever you make serious changes to your system, you may be fast enough to
see a message regarding 'ureadahead has been triggered'. This is the system
that collects all the initial  startup stuff into one area so it can be
quickly accessed. I've never had a better explanation than from the guy
responsible for it, back in 10.04 :)
