Thanks all for your contributions. I've settled on the following, after some experimenting: EMERGE_DEFAULT_OPTS="--jobs --autounmask=n --quiet-unmerge-warn --keep-going --nospinner" MAKEOPTS="-j24" I've stopped using disk space for /var/tmp/portage, even for the biggest packages, because (a) it causes a huge increase in compilation time, even on a SATA SSD, and (b) I've never seen an OOM anyway. So what if the system load goes high? It's only the number of processes ready for execution at any instant. I imagine the kernel is effective in guarding its own memory spaces. -- Regards, Peter.
