for salted algorithms, each plaintext candidate has to be hashed with each unique salt. therefore when cracking salted hashes, your effective speed is the total speed divided by number of unique salts. so if your single salt performance is 400 H/sec and you have 13681 unique salts, then your effective speed is 0.03 H/sec. the only way to speed this up is to eliminate salts as quickly as possible. this is accomplished by stacking your attacks in probabilistic order, so that you remove as many salts as possible in your first few passes.
