That is an interesting question; however, from running the program on
several different desktop computers, it seems to pick a block size that
takes about an hour to process -- so that it adjusts to the speed of the
processor. Over here, I've found that running on a Mac IIfx (40 MHz 68030)
goes at about 12 kkps, so it usesa block size of 2^26. On a 160 MHz PPC
603e, it uses a block size of 2^30, because that's how many it can do in
about an hour at 715 kkps.
So, the fast machines and the slow machines seem to report progress just as
often -- the faster machines just have more keys to check.
