On vanilla Pentium # performance improvement over compiler generated code reaches ~60%, # while on PIII - ~35%. On newer µ-archs improvement varies from 15% # to 50%, but it's less important as they are expected to execute SSE2 # code-path, which is commonly ~2-3x faster [than compiler generated # code]. SSE2 code-path is as fast as original sha512-sse2.pl, even # though it does not use 128-bit operations. The latter means that # SSE2-aware kernel is no longer required to execute the code. Another # difference is that new code optimizes amount of writes, but at the # cost of increased data cache "footprint" by 1/2KB. $0 =~ m/(.*[\/\\])[^\/\\]+$/; $dir=$1; push(@INC,"${dir}","${dir}../../perlasm");
