[bglug] Gentoo.it o .gentoo-italia.org ?

Qualcuno ( o qualch' uno :-) usa con *profitto* GenToo ?

Stavo provando a compilare tutto dallo stage 1, e mi sono accordo che ci
sono 2 siti di riferimento (per noi italiani) :
http://www.gentoo.it
http://www.gentoo-italia.org/
[ http://www.gentoo.org/doc/it/index.xml - il sito ufficiale, ha pochissimi
testi tradotti ! ]

Qualcuno li conosce e/o li frequenta ?
Sembrano simili (o sembrano TRATTARE argomenti simili) ...

A proposito, volendo ottimizzare la compilazione per una macchina
bi-processore P4 con 2 GB di RAM che cosa mi consigliate come settaggi ?
Questo e' quello + sensato che ho trovato !

[ a proposito http://www.gentoo.org/doc/it/faq.xml NON esiste,
http://www.gentoo.org/doc/it/gentoo-ppc-faq.xml invece ESISTE !]

I'm finding things to be really unstable and I'm using
"-O9 -ffast-math -fomit-frame-pointer" optimizations. What gives?
Don't bother using anything higher than -O3 since it isn't support by
current versions of gcc. Very aggressive optimizations sometimes cause the
compiler to streamline the assembly code to the point where it doesn't quite
do the same thing anymore.
A possible setting based on Loc-Dog (on IRC)'s :

CFLAGS
is -O3 -mcpu=i686 -march=i686 -fforce-addr -fomit-frame-pointer -funroll-loo
ps -frerun-cse-after-loop -frerun-loop-opt -falign-functions=4

which is about as much as I'd want to push global optimization settings.
Beyond this, it's best to use ultra-high optimizations only with specific
packages where you really need that extra 2%, (eg graphics and various
multimedia programs), and where you can easily test the package to ensure
that it hasn't been optimized into oblivion.
Please try first to compile with CFLAGS -march= -O2 before reporting a bug

Quando finisce di ricompilare ( _SE_ finisce :-) vi faccio sapere cosa
funziona e cosa no ...
