Hope you've got the problem with the current naming conventions for arguments and the result by going them. We should either document the arguments properly or change the code as i have pointed out. Since the iterations argument used properly in the case PBKDF2 (type8) within the same wrapper api gcry_kdf_derive.

Here's what i got from 1.8.1 code (downloaded from gnupg).

With the current implementation when the r is set to GCRY_KDF_SCRYPT, on a 3 core system, it almost took 35 minutes to generate the hash, where as with r=41 it was around 4 minutes and 20 seconds.
when i corrected the the values, i.e. N=16384, p=1 and r=GCRY_KDF_SCRYPT, it took less than a second to generate the hash.
