241 help
242 This adds a -jX option to certain packages that are known to
243 behave well for parallel build.
244
245 Note that this may overcommit CPU resources depending on the
246 -j level of the main make process, the number of package
247 submake jobs selected below and the number of actual CPUs present.
248 Example: If the main make is passed a -j4 and the submake -j
249 is also set to 4, we may end up with 16 parallel make processes
250 in the worst case.
251
252 You get maximum build performance, if you set the package build
253 jobs to the number of CPUs (cores) available and also start the main
254 make process with -jX, where X is the number of CPUs (cores).
255 However, make sure you have enough RAM available for
256 NR_CPUS to the power of two (NR_CPUS^2) make jobs.
