Optimizations beyond O2 (or even O1) most of the times do not make a
difference for the average user.
There is much randomness in the performance of an application caused
by things you cannot control, which have more influence on the
performance of the application
I watched a video about this not so long ago (it was about
optimization levels in gcc), which explained all this, but I'm unable
to find that again and unanble to reproduce what was being said there.
