Is there anything else I can measure during the kernel compiles?
Are the numbers for >= -pre6 slower because of measures taken to
increase the "interactivity" / responsivness of the kernel?

The part that looks most suspicious to me is that the results
for make -j100 vary so much ...

These are the additional infos from time -v for make -j100:

Well, yeah ... I suppose there's no point in getting greedy, is there?
