What hash type does that "slow" password file use? What hash type is
prevalent in your pot file? What version of JtR (and any patches) do
you use?
My guess is that you're dealing with saltless hashes, and that the
corresponding *_fmt.c file (coming from a patch) does not provide proper
binary_hash[]() functions.
If so, you may consider improving that *_fmt.c file and/or you may use
the workaround suggested in this posting:

The piece of code quoted in that posting is normally very fast, but it
becomes very slow under conditions mentioned above. If so, it may be
dropped (commented out) with little harm. Please also see these
follow-up postings:

Please let the list know if you try making this change and whether it
helps (and how much) or not.
Thanks,
Alexander
