Another problem is that formats which used to distinguish between "Many
salts" and "Only one salt" or short and long passwords in a previous
release don't in a new release and vice versa.

$ grep -A 2 "HMAC MD5" j?-sse*

Don't ask me why this format got slower (on 32 bit linux, with sse2i and
OMP).
The point is, I had just one benchmark result in jumbo-5, now I have 2.
