This was the build time on make -kj25:
321.67user 105.39system 11:08.05elapsed 63%CPU (0avgtext+0avgdata 
0maxresident)k
0inputs+0outputs (209major+7874919minor)pagefaults 0swaps
Load average was around 8-9 most of the time and the compilation 
succeeded.

For unsemake --compile-jobs=25 -k, this was the build time:
294.79user 150.16system 11:03.03elapsed 67%CPU (0avgtext+0avgdata 
0maxresident)k
0inputs+0outputs (110major+13870575minor)pagefaults 0swaps
Load average was around 9-11, but the compilation failed (it went as far 
as linking libDCOP.la). This is the first error that I noticed (I might 
have let others slip by):
/home/tjmaciei/src/kde4/KDE/kdelibs/kabc/kab/../addressbook.h:29:23: 
error: addressee.h: No such file or directory

To get another comparison, I compiled KDE Libs 3.5:
665.60user 273.01system 22:38.50elapsed 69%CPU (0avgtext+0avgdata 
0maxresident)k
0inputs+0outputs (256major+38426195minor)pagefaults 0swaps
Load average between 9-11 too.

That's TWICE as long. There's some linking happening before, but ~11 
minutes into the build, it does only linking. So that's another 11 
minutes linking!

(The compile farm was never saturated in any case.)
