Post #2353288

@Mehrad@fosstodon.org By default Guix tries to feed the guix build systems with the number of cores available. Generally, most derivations will be built using all your available cores. The thing is that the underlying build systems will or will not make an efficient use of those cores. For example, the `gnu-build-system` will take all your cores and pass them to `make`. If `make` does not make an efficient use of those cores, you can use the `-M ` flag to build multiple derivations in parallel.
