That's very nice.

Yes, it might further improve performance at MD5 and Blowfish-based
hashes, but it should not make a difference at DES-based crypt(3) hashes
(because those almost exclusively rely on the SSE2 code) and it might
affect LM hashes in a "random" way.

Thank you!  You entered the wrong number in place of the single-salt
benchmark, though - I've corrected this.


P.S. I was on vacation, and I am still not done with my backlog of
e-mails.  So please don't be offended by lack of replies from me.  Also,
I have two independent updates of the jumbo patch to in my
mailbox, so please don't spend your time on making yet another one (or
upload it to the wiki such that your work actually benefits the
community right away).  I will release such an update eventually.
