Multiforcer and LM

[pyr]

Hi,
I am using Cryptohaze Multiforcer to bruteforce some LM hashes, I get a speed of about 80M/s.
MD5 or NTLM speed is about 400M/s !
Why does LM so slow ?

Thank you.

We just had this discussion...

LM is DES based, not MD4 based. DES is a whole lot "harder" than MD4.

Also, if you're running a GTX260 with a lot of hashes, try adding the "-l" switch. It creates a large bitmap in main memory. It's not on by default for pre-Fermi because a lot of them don't have enough memory for that plus everything else.

Sorry for duplicate topic, you can delete mine.

Ok I'll try -l switch, thank you.
