Yep. We increased to 10Gkeys (from 5 Gkeys) in less than a month.
When we started rc5-56 the fastest intel there was was a ppro 200 or
so. Now we're dealing with pII-300 and more. Ghz is coming fast....
So a speedup of 10^2 should be doable. And then it's one year to
finish rc5-64. That's reasonable, not?
