264 This adds a -jX option to certain packages that are known to
265 behave well for parallel build.
266
267 Note that this may overcommit CPU resources depending on the
268 -j level of the main make process, the number of package
269 submake jobs selected below and the number of actual CPUs present.
270 Example: If the main make is passed a -j4 and the submake -j
271 is also set to 4, we may end up with 16 parallel make processes
272 in the worst case.
273
274 You get maximum build performance, if you set the package build
275 jobs to the number of CPUs (cores) available and also start the main
276 make process with -jX, where X is the number of CPUs (cores).
277 However, make sure you have enough RAM available for
278 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
