- help
- This adds a -jX option to certain packages that are known to
- behave well for parallel build.
-
- Note that this may overcommit CPU resources depending on the
- -j level of the main make process, the number of package
- submake jobs selected below and the number of actual CPUs present.
- Example: If the main make is passed a -j4 and the submake -j
- is also set to 4, we may end up with 16 parallel make processes
- in the worst case.
-
- You get maximum build performance, if you set the package build
- jobs to the number of CPUs (cores) available and also start the main
- make process with -jX, where X is the number of CPUs (cores).
- However, make sure you have enough RAM available for
- NR_CPUS to the power of two (NR_CPUS^2) make jobs.
