On newer µ-archs improvement varies from 15% 50# to 50%, but it's less important as they are expected to execute SSE2 51# code-path, which is commonly ~2-3x faster [than compiler generated 52# code]. SSE2 code-path is as fast as original sha512-sse2.pl, even 53# though it does not use 128-bit operations. The latter means that 54# SSE2-aware kernel is no longer required to execute the code. Another 55# difference is that new code optimizes amount of writes, but at the 56# cost of increased data cache "footprint" by 1/2KB. 57 58$0 =~ m/(.*[\/\\])[^\/\\]+$/; $dir=$1; 59push(@INC,"${dir}","${dir}../../perlasm");
