246 help
247 This adds a -jX option to certain packages that are known to
248 behave well for parallel build.
249
250 Note that this may overcommit CPU resources depending on the
251 -j level of the main make process, the number of package
252 submake jobs selected below and the number of actual CPUs present.
253 Example: If the main make is passed a -j4 and the submake -j
254 is also set to 4, we may end up with 16 parallel make processes
255 in the worst case.
256
257 You get maximum build performance, if you set the package build
258 jobs to the number of CPUs (cores) available and also start the main
259 make process with -jX, where X is the number of CPUs (cores).
260 However, make sure you have enough RAM available for
261 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
