[hashcash] Re: 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).

I unearthed an old CD which happened to have my old hashcash-1.08 binaries on it. This achieves over 10 Mh/sec per CPU on my 2.3GHz G5 - without any fancy GCC4 tricks, and possibly even lacking some of my later optimisations. Thus, as I've just set off a pair of 40-bit minters on it, I expect to have a result in about 14 hours' time.
