Openwall cracker ?!

[Mem5]

Considering oclhashcat last version and this command line :

Code:

-a 3 -m 3000 -n 160 --markov-disable -i --increment-min 1 --increment-max 7 -1 ?u?d?s 1000_hashes.txt ?1?1?1?1?1?1?1

Speed is ~1200 Mh/s, duration ~1h30.
ATI 7970

1/ Any hints to speed it up ?
2/ is "?u?d?s" the same behaviour as "?a" when bruteforcing LM ?

Thank you.
