Benchmark vs Mask NTLM - tsk0 - 10-08-2018
Hi everyone,
I tried searching the forum for some guidance on the difference (if any) and could not come up with anything definitive.
Basically I'm trying to understand the significant difference I'm getting between the benchmark and a password mask for ?a?a?a?a?a?a?a?a
The benchmark suggests 60,837MH/s (66GH?/s) but when performing actual work it's only doing ~30,000 MH/s . Is this inline with typical real world performance or is something seriously busted :/
Using 4.2.1
Benchmark:
Hashmode: 1000 - NTLM
Speed.Dev.#1.....: 32759.2 MH/s (60.68ms) @ Accel:256 Loops:512 Thr:1024 Vec:2
Speed.Dev.#2.....: 33077.8 MH/s (60.06ms) @ Accel:256 Loops:512 Thr:1024 Vec:2
Speed.Dev.#*.....: 65837.0 MH/s
Mask Attack
Command: hashcat -m 1000 -O -a 3 -w 4 output.ntds ?a?a?a?a?a?a?a?a
Guess.Mask.......: ?a?a?a?a?a?a?a?a [8]
Guess.Queue......: 1/1 (100.00%)
Speed.Dev.#1.....: 15437.0 MH/s (249.24ms) @ Accel:256 Loops:1024 Thr:1024 Vec:2
Speed.Dev.#2.....: 15656.7 MH/s (245.88ms) @ Accel:256 Loops:1024 Thr:1024 Vec:2

Trying to find info on overclocking and found this post; so yeap...it's expected (multihash).

Your cards are overheating. Find a way to cool them better.

The issue here is you're trying to compare single hash performance to multi-hash performance. Apples vs. oranges.

Hi epixoip,
Yeap, you said the same in that other thread I linked above . Do you think it's worthwhile putting that info on the wiki or FAQ somewhere.

Sorry, didn't see that reply. Kind of got lost in the wall of quoted text. In the future, please do not quote other people's posts in your reply unless doing so adds significant value to your reply. And even then, please only quote the relevant portion. Like this:

It kind of is covered on the FAQ: https://hashcat.net/faq#why_is_my_attack_so_slow
