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

276 packages with multiple jobs that are probably not tested in
277 a parallel build environment.
