GMP performance on Opteron 

Hi,

For the following command

setrand(1);rnfisnorminit(y^2+29*y+21,x^3-10*x^2-3*x-5);

GMP kernel gives a visible performace advantage on 64bit Sparc
Solaris and 32 bit ix86 Linux over non-GMP kernel, but is slightly
slower than non-GMP on Opteron.  Any idea why?

Thanks

Igor
