Hi, Most of SUSE specfiles include %{?jobs:-j%jobs} for parallel execution. It is also a well-known fact that quite some time is spent with setting up roots, etc., and compiling projects that can only do -j1. To keep the machine busy, I would increase the number of parallel build instances running. Furthermore, to not let parallel building go out of hand, I would switch from make -jX to make -lX. This would be straightforward to change in .rpmmacros (and/or build's equivalents, respectively): %_smp_mflags -l24 SUSE's specfiles however use a hardcoded %{?jobs:-j%jobs} (historic reasons?) which makes it impossible to easily change to other make flags. I could try touching the $MAKEFLAGS environment variable, but that may as well be reset, ignored, or whatever. In other words, I would prefer -l24 on the command-line. To that end, I am suggesting to change all %{?jobs:-j%jobs} found in specfiles by %_smp_mflags. It should be possible to do this in an automated fashion — projects which are not using -j%jobs in the first place (e.g. because they just are not capable) will not be affected anyway. N.B.: watch out for scons %{?jobs:--jobs=%jobs} which uses --jobs instead of -j. Thoughts?
