On newer -archs improvement varies from 15% 27 # to 50%, but it's less important as they are expected to execute SSE2 28 # code-path, which is commonly ~2-3x faster [than compiler generated 29 # code]. SSE2 code-path is as fast as original sha512-sse2.pl, even 30 # though it does not use 128-bit operations. The latter means that 31 # SSE2-aware kernel is no longer required to execute the code.
