259 This adds a -jX option to certain packages that are known to
260 behave well for parallel build.
261
262 Note that this may overcommit CPU resources depending on the
263 -j level of the main make process, the number of package
264 submake jobs selected below and the number of actual CPUs present.
265 Example: If the main make is passed a -j4 and the submake -j
266 is also set to 4, we may end up with 16 parallel make processes
267 in the worst case.
268
269 You get maximum build performance, if you set the package build
270 jobs to the number of CPUs (cores) available and also start the main
271 make process with -jX, where X is the number of CPUs (cores).
272 However, make sure you have enough RAM available for
273 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
