Sure, I've used per-package optimizations myself in some particular cases, but that's not the point. A package manteiner *should* know better than an average user which optimizations will tune better their own package. My question can be put like this: Do binary distro's per package optimiziations override the benefit of having arch specific optimiziations that gentoo allows? =3D=3D=3D=3D=3D=3D=3D TopperH =3D=3D=3D=3D=3D=3D=3D --PuGuTyElPB9bOcsM Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAkmJmK4ACgkQTusdC+HYtiJTagCg72f7DXoXaKYFZkg4CTb8fNI2 wncAn2ayc9wSZ0enN6syLGoWrsgD4876 =GfHo -----END PGP SIGNATURE----- --PuGuTyElPB9bOcsM--
