Hi all..
Certainly some package have a maximun optimisation. I really believe, the optimisation level is a very interesting thing bucause all depend of what you need and you have all power of your system, only gentoo can give you that.
it's very good to see a server compiling most of the applications, and people with few resources in thier pc's can run a very good operating system and no die trying... :P
Looking for more information on the web, I see
http://www.linuxjournal.com/article/7269.
In that article: "...The simplest way to achieve good performance is to rely on the -O2 optimization level;
if you're not interested in portability, specify the target architecture using -march=. For space-constrained
applications, the -Os optimization level should be considered first.."
All is your decision based in what you need...

Some packages (ebuilds) set a maximum optimisation. Gcc is one of them,
OpenOffice another one.
