Re: [Monotone-devel] Fast SSSE3 based SHA-1 by Intel

[Jack Lloyd]

Thanks! I'll look into implementing this optimization; monotone
already uses the SSE2-based optimizations when possible, but SHA-1
computions are a fairly core operation (the compression function is
about 8% of the total runtime on many operations, IIRC) so any new
improvements are a plus.

Regards,
  Jack
