gcc performance

Dear managers,

we are about to purchase a new machine for our dev department (Window
Maker, gcc, Sun Ray Server, database,...) and therefore have done some
performance tests on the following machines.

Sun Fire 240
CoolThread T2000

Building gcc with the gcc (supplied by Sun) we got the following
results:

Sun Fire 240: 40 min
T2000: 117 min

We have expected the T2000 (1GHz) to be slower than the 240 (1.5GHz)
but we have not expected such a big difference. Why is the 240 three
times faster? It is obvious that gcc and gnu make are building the
sources file by file and that thus only one core is utilized. Is it
somehow possible to distribute the workload over the cores? I know that
Apple very recently has introduced this feature in their xCode. I was
wondering whether and how this would be possible under Solaris with
plain gcc and gnu make.

Thanks a lot!

Regards,

Andreas
