Hum, since I expect disagreements on the changes, I propose to split
the patch into two parts: minimum change to optimize, and a second
change (later, once the first one is merged) to cleanup further the
code.

"Some changes don't affect performance"

Well, a cleanup is supposed to not affect performances at all :-)
