Related - rpm has tunables that allows you to tune the build according the available resources. However memory is not there:
https://github.com/rpm-software-management/rpm/pull/2418
https://rpm-software-management.github.io/rpm/manual/buildprocess.html
Oh, nice, I didn't know about that! From a quick look, there are actually two memory tunables, %_smp_tasksize_proc and %_smp_tasksize_thread.
Looks like the new thing would replace the constrain_build macro that firefox.spec is using:
Instead of current:
# Require 4 GB of RAM per CPU core
%constrain_build -m 4096
It would use:
# Require 4 GB of RAM per CPU core
%global _smp_tasksize_proc 4096
It doesn't look like a huge win from the packager's point of view, but I am sure it's better to use the rpm upstream limits instead of external macros such as constrain_build.
