#irreal and @bbatsov about #Emacs startup time: https://irreal.org/blog/?p=12903
I, too, am totally convinced that it really doesn't matter if it is one or sixty seconds.
However, if your bootup time is much longer than mine (15-30s once a week) then you most probably have room for improvement (if you want). Consistent use of #usepackage with dependencies and "defer" did help on my side.
My config has 7724 lines of #elisp (19851 including #orgmode comments): https://github.com/novoid/dot-emacs/blob/master/config.org
