268 This adds a -jX option to certain packages that are known to
269 behave well for parallel build.
270
271 Note that this may overcommit CPU resources depending on the
272 -j level of the main make process, the number of package
273 submake jobs selected below and the number of actual CPUs present.
274 Example: If the main make is passed a -j4 and the submake -j
275 is also set to 4, we may end up with 16 parallel make processes
276 in the worst case.
277
278 You get maximum build performance, if you set the package build
279 jobs to the number of CPUs (cores) available and also start the main
280 make process with -jX, where X is the number of CPUs (cores).
