I've got a first generation i7 and this is what I have set up in my make.co= nf: MAKEOPTS=3D"-j5 -l12.8" EMERGE_DEFAULT_OPTS=3D"--quiet-build=3Dn" Why is -l set at 12.8 ... ? At some distant point in the past this made se= nse=20 to me, but I have no idea how I arrived at it. Other than the cooling fan= =20 speeding up I have not noticed a problem with any ebuilds. Very rarely I=20 might have used -j1 to complete a failing ebuild, but it was so long ago I= =20 can't even recall it. =2D-=20 Regards, Mick --nextPart6321910.4jnCjHf8ho Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iEYEABECAAYFAlFVivkACgkQVTDTR3kpaLbCMQCcCa6DQZdsHLH/9QM2R2pz0xRL HDsAn0/S7VCmjyYHPQeetP1cUoGJ9flq =nTgw -----END PGP SIGNATURE----- --nextPart6321910.4jnCjHf8ho--
