This branch is quite ahead of the branch Stefano's used. There are 94 
commits more just for Arm specific code.

What I am interested is to see if we are able to reproduce Stefano's 
number with the same branch. So we can have a clue whether there are a 
slow down introduce in new code.

Stefano, you mention you will look at reproducing the numbers. Do you 
have any update on this?

Cheers,
