Sorry, I meant "roughly identical [to my Go program]", not "roughly identical [to the version without OpenSSL]". The ~/verify binary is my little Go program that is ~4 times faster on my Void system, but is of roughly equal performance on the Arch system, to check that coreutils is not slower than Go (when using OpenSSL). Sorry, I probably didn't make that too clear.

Ah, I should have guessed from the program name. :)

I thought I remember Go having pretty optimized assembly for crypto routines. But I have not used the language much. If you have your source code uploaded somewhere I'd be interested to have a look to see what I am missing out on.
