  Thanks a lot: that is very interesting, I cannot wait!

Results from Pentium 3, 800MHz.  That CPU was released late 1999 and was
then "state of the art".

GMP 2.0.2: 6460/6352
GMP 6.1.2: 2391/2278

We haven't done uch in the way of improving GMP for 32-bit x86 in the
last 10 years.  If an effort were made, I guesstimate that GMP could run
25% faster on these old CPUs.
