[hashcash] stamp speeds on new hardware

bas sent me a 40-bit stamp... nice:

        1:40:051210:beware@xxxxxxxxx::qsCVFGF+ZkcA/B63:SNSrr

took 28 hours on the pair of below machines with 2 cores used on the
athlon64 x2.  (I think the p4 prescott 3.6Ghz does not have
hyperthreading).


The stats for those machines:

        http://www.hashcash.org/benchmark/

4.68 Mh/s       0.22s   2.2Ghz  athlon64 x2     mmx std 1x2

3.9 Mh/s        0.27s   3.6Ghz  P4 prescott     mmx std 1x2

That is one core on the athlon64 so a single athlon64 x2 with both
cores slightly outperforms the 2Ghz G5.

But I would think assembler targetted at the 64 bit athlon + any 64
bit mmx / sse variant should get a boost on a 64bit vs 32bit athlon?
