| 223 | This adds a -jX option to certain packages that are known to |
| 224 | behave well for parallel build. |
| 225 | |
| 226 | Note that this may overcommit CPU resources depending on the |
| 227 | -j level of the main make process, the number of package |
| 228 | submake jobs selected below and the number of actual CPUs present. |
| 229 | Example: If the main make is passed a -j4 and the submake -j |
| 230 | is also set to 4, we may end up with 16 parallel make processes |
| 231 | in the worst case. |
| 232 | |
| 233 | You get maximum build performance, if you set the package build |
| 234 | jobs to the number of CPUs (cores) available and also start the main |
| 235 | make process with -jX, where X is the number of CPUs (cores). |
| 236 | However, make sure you have enough RAM available for |
| 237 | NR_CPUS to the power of two (NR_CPUS^2) make jobs. |
| 238 | |
| 239 | If you are unsure, select N. |
