301 This adds a -jX option to certain packages that are known to
302 behave well for parallel build.
303
304 Note that this may overcommit CPU resources depending on the
305 -j level of the main make process, the number of package
306 submake jobs selected below and the number of actual CPUs present.
307 Example: If the main make is passed a -j4 and the submake -j
308 is also set to 4, we may end up with 16 parallel make processes
309 in the worst case.
310
311 You get maximum build performance, if you set the package build
312 jobs to the number of CPUs (cores) available and also start the main
313 make process with -jX, where X is the number of CPUs (cores).
314 However, make sure you have enough RAM available for
315 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
