Hi Len, 

yes, that is the point, I wanted to know. I suppose, higher than "-j 4" will 
let the system make too slow. 

Just another last: Are the entries in /etc/apt/apt-build.conf used by any(!) 
compiler applications, which are debian based ? I am thinking especially of 
commands like "make-kpkg", ncurses tools  like "module-assistant" and dpkg 
related things, which are executed during upgrading of packages.
