Ok. After some massive rebooting:

-J2 is worser. starting XFree(+gnome) when three gcc's are running
take long (> half a minute?). With -J5 X start nearly normal (mostly
file access time anyway?) Dragging windows arround is nearly
equal. Although with -J2 i sometimes noticed a really big latency when
starting vim or man ...

Oh. btw. The -J5 was tested with 2.4.18-pre7; the rest was with
vanilla-2.4.17 - I hope this doesn't make a performance difference for
this tests ...
