oclHashcat v1.33 speed drop
#6
Here's the log that I had with undeath, it explains it in detail:

Quote:18:28:25 undeath | atom: it really seems something messed up from 1.31 to 1.32, cudaExample0 is almost twice as slow
18:30:56 @atom | nope its just optimized for fast systems
18:31:04 @atom | on fast ones its nearly twice as fast
18:32:03 undeath | what is a "fast" system?
18:32:27 @atom | well, a 7970 for example
18:32:33 @atom | nothing crazy
18:33:05 undeath | but if it's almost twice as slow with a 750ti something sounds off
18:40:48 @atom | root@et:~/xy/oclHashcat-1.31# ./oclHashcat64.bin -t 32 -a 7 example0.hash ?a?a?a?a example.dict --keyspace
18:40:48 @atom | oclHashcat v1.31 starting...
18:40:49 @atom | 1048576
18:40:55 @atom | root@et:~/oclHashcat-1.34# ./oclHashcat64.bin -t 32 -a 7 example0.hash ?a?a?a?a example.dict --keyspace
18:40:55 @atom | oclHashcat v1.34 starting...
18:40:56 @atom | 129988
18:41:02 @atom | thats the difference
18:41:26 @atom | in -a 7 mode, in 1.31, it used the mask as base
18:41:36 @atom | so it can parallel more
18:41:53 @atom | that changed with 1.32, because if you do -a 7 attack, you usually use bigger dictionaries
18:42:10 undeath | mhm, but still, 96s vs 165s is pretty hefty
18:42:22 @atom | no
18:42:23 undeath | 1.33 was even slower than that with 193s
18:42:44 @atom | its just hypothetical#
18:42:49 @atom | in reality, 1.33 will be faster
18:43:01 undeath | that was reality >.>
18:43:13 @atom | no its an example script
18:43:18 undeath | Tongue
18:43:35 undeath | let me try a bigger dict
18:44:29 @atom | rockyou should be sufficient
18:45:03 undeath | yeah, just started with rockyou
18:45:15 @atom | you can even stick to example.dict
18:45:21 @atom | just remove 1 ?a from the mask
18:45:24 @atom | so only ?a?a?a

IOW, replace example.dict with rockyou and everything is fine
