Reboot. If there are two penguins, there are two procs.
But more seriously, you can make the kernel tree. I
once had a dual-1333Mhz Athlon setup, and adding the
second processor sped up make times by about 80%.
time make -j3 bzImage
the -j option specifies the number of compile jobs to
run simultaneously, 3 is a good number for two procs - it
makes sure that there is at least one gcc per proc.
the time command tells you the total time
(user, system, total) for the make. Compare
times for one, two procs (may require recompiling the
kernel for uniprocessor).
