Bonjour,
J'utilise gentoo depuis un petit moment maintenant et j'ai essayer la version 64bits no-multilib sur mon dell d630.
je m'etonne de voir que par exemple firefox 3.0.3 consomme environ 600Mo de memoire virtuelle alors que sur la meme machine sur un gentoo 32 bits il en consomme "a peine" 150Mo
meme probleme avec thunderbird.

voici mon make.conf

# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /etc/make.conf.example for a more detailed example.

Salut et bienvenue ici ! Peux-tu mettre ton titre du topic en conformité avec les conventions de notre forum s'il te plait ? Merci :)

Perso j'ai jamais vu de différence de consommation entre la version 32bit et la 64bit, c'est un monstre en consommation de ram dans les 2 cas. Par contre, si t'utilises le flash proprio avec le multilib et tout, n'oublie pas que du coup ça te charge les libs 32bit en plus de celles déjà chargées en 64bit, donc ça double la taille totale du binaire :P (ha que c'est beau le monde propriétaire...)
Perso je n'ai ni le flash proprio, ni le multilib, donc pas de soucis de ce coté, et en ce moment même il ne consomme "que" 220MiB de ram... :P

Euh, il n'y a pas pas comme un problème là ?
Pour du 64bits, le CHOST ne serait-il pas x86_64-pc-linux-gnu plutot que i686-pc-linux-gnu ?
T'es sur d'être en 64 bits ? Ou alors tu nous as pas donné le bon make.conf
