Yep. I mentioned that coreutils/TODO wrt md5sum:
Look into improving the performance of md5sum.
`openssl md5' is consistently about 30% faster than md5sum on an idle
AMD 2000-XP system with plenty of RAM and a 261 MB input file.
openssl's md5 implementation is in assembly, generated by a perl script.
I suspect their sha1 code is similar.
I'd welcome patches to improve the performance of either.
OK, I'll have a look. FreeBSD seems to be faster again,
(don't compare these results to the previous mail):
