I'm very surprise to see the differences between these two same benchmarks
on shootout.alioth.debian.org :
1) Quad core :
2) Mono core :

Here are the CPU times :
1) 2095.18 s
2) 37.03 s

I try on my machine[1] with a) "-smp enable" and b) "-smp disable" :
a) 47.863 s
b) 18.285

Maybe It's not strange to see a such difference because of inter-cpu message
passing. But the difference on shootout.alioth.debian.org is too large
What should we do ?
