I supposed that!

I agree with everything. In any case I think that a faster compiling will 
really be a good thing.
I have been reading another time the man of make.conf and I still have some 
doubts.
Neither in the example either in the man page there is any reference to 
"MAKEOPTS". Changing from -j1 to -j3 would really be a huge difference! 

To be able to set this is very important. 
Then I don't want an ultra tweaked make.conf like gentooers do. Just a 
reasonable one. 
(And you have convinced me, I won't recompile everything. Just to have a good 
compiling when I will be upgrading)

I have some doubts about the correct syntax, the man is ambiguous in this point.
If I write CPUTYPE= core2 will it automatically sets all the best safe CFLAGS 
for my core or just set the -march=core2
Should my make.conf be  like:
MAKEOPTS==-j3
CPUTYPE=core2
CFLAGS= --O2 -pipe -fno-strict-aliasing

or just:
MAKEOPTS==-j3
CPUTYPE=core2

or maybe:

MAKEOPTS==-j3
CPUTYPE=core2
CFLAGS+= --O2 -pipe -fno-strict-aliasing

Actually that's really funny!! I think that's why there are so many pages about 
gentoo and almost none about other OSes.
