I'd done this experiment sometime ago, and I had sent a mail here as well regarding which load average does make account for. A couple of packages started failing compile and it turns out that they don't work well with the infinite jobs that make --jobs spawns. It's better to limit the number of jobs to 2*CPUs (or cores) with a load control like --load-average=N where N is number of CPUs. https://bugs.gentoo.org/show_bug.cgi?id=452942 -- Nilesh Govindrajan http://nileshgr.com
