Three companies I worked at have routinely used
-j 2*number of CPUs, even on shared machines
(some of which had 15 CPUs).

If the -l (max load average) option works as
advertised, perhaps -j without arguments should
imply -l number-of-cpus?  That seems like it
would maximize an individual's
throughput while also adaptively dividing
up a shared build machine.

I have never tried -l, though.
