OK, as promised to psychicist and to you guys, here goes the result of my "experiment". First I compiled KDE 4.1.1 using 'make -j4' and it took 136m3.569s (136 minutes and 3.569 seconds); then I tried 'make -j8' and it took 126m16.009s (126 minutes and 16.009 seconds).
Now, you tell me. What's best, '-j4' or '-j8'? ;)
Ok, enough geek talking for today ;)
Ah, sure! I promised the URL for you to download KDE 4.1.1 packages for Bluewhite64, right? There you go: http://data.linux64packages.net:8080/bluewhite64-12.1/kde-4.1.1/kde/
