I finally saw Citizenfour, and the voiceover at the beginning said to
assume that a they can try a trillion keys a second. That would be the
US government, ~3-years ago, in a case where they are really pissed.
Other cases would be slower.
Looking at hashcat speeds
(https://gist.github.com/epixoip/a83d38f412b4737e99bbef804a270c40) on an
8-GPU system (pretty affordable for many values of "medium"), is a lot
slower, but dang impressive. The comments say the PBKDF2 numbers are all
1,000-rounds, I don't know which matches your proposal.
