Tony, |
| 19 |
Some ebuilds filter out MAKEOPTS="-jX" because the makefile(?) is not |
| 20 |
written correctly to compile with more than one concurrent compile |
| 21 |
process. According to the OOo ebuild, -jX is not filtered, so that is |
| 22 |
not the case. Also, you may have checked the CPU usage when it was |
| 23 |
extracting the tarball, obviously the choke point here would be the HD, |
| 24 |
not the CPU. |
| 25 |
|
| 26 |
Just some extra info for you, I am not the ebuild expert. HTH |
