>I guess 32-bit x86 performance is maybe not the best benchmark. I compiled for 32bit instead of 64bit because I wanted the same executable to also run on a 32bit Macbook. When Thomas Pornin ran benchmarks[1] in 2010 for both 32bit & 64bit, the SHA256 hash performance didn't change as much as the SHA512. I'll recompile for 64bit and report back if there was a massive difference.
