I'd suggest blake2sp. It's currently the fastest on my machine, and I
guess that there will often be multiple cores in systems where hash
performance matters (i.e. hashing large files or many files).

But, if for some reason blake2sp is problematic, then any of the other
BLAKE2 variants would also work.

It seems like we can get people to migrate off of MD5 by offering them
better performance *and* improved security, but not by offering them
worse performance and improved security.
