I guess the figures are from some kind of suboptimal (MSVC?) 32-bit build so only the relative figures are interesting. My unmodified aix-ssha does 12990 c/s versus Jim's original figure of 4629. Optimistically hoping for same relative boost, I'd get 207543K c/s with SSE2 which would translate to over 27M SHA1/s. That's better that Tavis' raw-sha1 (like it should).
