Hi...
And thanks for the suggestions.
I have now tested with -j option and i can confirm that my expectations
are correct the Dual CPU dual core AMD completes the buildworld with -j4
in one hour only, while the intal core 2 does it in 1h30m
should i stick the -j option in the make.conf?

If I read you right, you didn't ``make -jX buildworld'',
with X being the number of processes to spawn,
so you used just one core on either machine.
Buildworld does a lot of I/O, so disk speed is relevant.
Yes, i just made "make buildworld".
So i should use make -j2 on the S1(dual core) and -j4 on S2
(2xdualcore)?
And it also makes sense what you say about the I/O.
It really depends on the system. On my dual-core systems, I use
devel/ccache and found that -j8 gave the best performance.
