The module is dual licensed under OpenSSL and CRYPTOGAMS +# licenses depending on where you obtain it. For further details see +# https://github.com/dot-asm/cryptogams/. +# ==================================================================== + +# SHA256/512 for PowerISA v2.07. +# +# Accurate performance measurements are problematic, because it's +# always virtualized setup with possibly throttled processor. +# Relative comparison is therefore more informative. This module is +# ~60% faster than integer-only sha512-ppc.pl. To anchor to something +# else, SHA256 is 24% slower than sha1-ppc.pl and 2.5x slower than +# hardware-assisted aes-128-cbc encrypt. SHA512 is 20% faster than +# sha1-ppc.pl and 1.6x slower than aes-128-cbc. Another interesting +# result is degree of computational resources' utilization. POWER8 is +# "massively multi-threaded chip" and difference between single- and +# maximum multi-process benchmark results tells that utilization is +# whooping 94%. For sha512-ppc.pl we get [not unimpressive] 84% and +# for sha1-ppc.pl - 73%. 100% means that multi-process result equals +# to single-process one, given that all threads end up on the same +# physical core. +# +###################################################################### +# Believed-to-be-accurate results in cycles per processed byte [on +# little-endian system].
