296 This adds a -jX option to certain packages that are known to
297 behave well for parallel build.
298
299 Note that this may overcommit CPU resources depending on the
300 -j level of the main make process, the number of package
301 submake jobs selected below and the number of actual CPUs present.
302 Example: If the main make is passed a -j4 and the submake -j
303 is also set to 4, we may end up with 16 parallel make processes
304 in the worst case.
305
306 You get maximum build performance, if you set the package build
307 jobs to the number of CPUs (cores) available and also start the main
308 make process with -jX, where X is the number of CPUs (cores).
309 However, make sure you have enough RAM available for
