Compiler optimisations matter. However it’s not a silver bullet to fix the world. I ran a little experiment, and you can read more about it.

There has been lot of discussion about compiling GNU/Linux from scratch, and performance boost related to it. I have never been a big believer of this – except for applications such as multimedia encoding. How much does optimisation really matter?

From what I learned, optimising for athlon-xp (or i686) instead of i386 will get you around 15% performance boost with processing multimedia content, but for amd64 it’s all the same.
