I guess we can douple or triple the performance but not much more.
The whole point of the algorithm is to slow things down.

Things to do: Avoid the overhead of the cyptoframe work and thus write
an optimized hash function. Avoid dynamic memory allocation and reuse
buffers.  And all the other usual micro optmimizations.  It does not
make much sense unless you want to write a passphrase cracker, though.
