I find that "4" is the right thinking number for my dually.
Here is a snip from a mail i sent to this list April, 99:
---------------------------------------------------------------------------
Regarding the `make -j` discussion a while back, here are my measured times
on a dual PPro/200 128MB aic78xx libc5 K:2.2.0-final (building 2.2.5)
1 7:48
2 4:42
3 4:37
4 4:32
5 4:32
6 4:36
7 5:05
8 5:56
-j 13:26
---------------------------------------------------------------------------
Also note that as in davem's shell script, it is more correct to do
make MAKE="make -j4" bzImage
rather than
make -j4 bzImage
IIRC, glibc2 wouldn't build with -j > 1.
