If attacker attempts to crack one encrypted filesystem with or without -S option, he has to: 1) Compute passphrase hash values for every passphrase in dictionary. 2) Try each hash for filesystem Without -S option, attacker can use CPU cycles to compute step 1 in advance, but that does not decrease the total amount of CPU cycles he has to spend. -S option only time-shifts the earliest time _when_ those CPU cycles need to be used.
