Problems with benchmark

[damien]

Hi All,

I am running a RIG with 3x RTX 3070, Windows 10, and 64 GB RAM, and I am trying to recover a NTLM password from my own test environment.

The benchmark results are as follows:
Hashmode: 1000 - NTLM

Speed.#1.........: 71330.4 MH/s (42.03ms) @ Accel:64 Loops:1024 Thr:1024 Vec:8
Speed.#2.........: 71046.4 MH/s (42.23ms) @ Accel:64 Loops:1024 Thr:1024 Vec:8
Speed.#3.........: 72190.0 MH/s (41.51ms) @ Accel:64 Loops:1024 Thr:1024 Vec:8
Speed.#*.........:  214.6 GH/s


But, when I perform some cracking, the performance is a little bit disappointing, and will not get 214 GH/s

What am I doing wrong, any suggestions ?

There is nothing really wrong here, the keyspace is quite small (as you can see it takes only 4 seconds to complete).

Though there are some things you can do, use -w3 or even -w4, and use -O when possible.

Instead of using only uppercase, I have changed my keyspace into a:

The 'real' speed is still the same. Even when I add -w 3 or 4, it is only 62000 M, so why don't I get the full speed of 212 G ?

[Xanadrel]

Again, read carefully what I said, I didn't mention only -w param, but also -O.

[damien]

adding -O does the trick.

Hi all.
I have problems on linix and wondows:
on algo SCRYPT not speed.

It's not a problem, it's literally that slow with whatever hardware you're using with that many iteration count.
