In: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#book_part1_chap5 I can read: "MAKEOPTS With MAKEOPTS you define how many parallel compilations should occur when you install a package. A good choice is the number of CPUs in your system plus one, but this guideline isn't always perfect." Then, for my dual-core system, -j3 seems ok (this is the one I am using now) While in http://www.gentoo.org/doc/en/distcc.xml#doc_chap2 , I can read: "# emerge distcc # nano -w /etc/make.conf (Set N to a suitable number for your particular setup) (A common strategy is setting N as twice the number of total CPUs + 1 available) MAKEOPTS="-jN" (Add distcc to your FEATURES) FEATURES="distcc"" Then, maybe -j5 would be better. I don't know wich is the best option, but I think that they should say the same instructions Thanks :-) Reproducible: Always
Distcc is a special case; it is only for when you are sharing the build process across more than one _machine_, not more than one CPU in a _single_ machine.
