Subject: Performance problem running on gpu (windows 10)
I have a computer with a gpu that I am trying to use with john the ripper.
I am using john_bleeding_2024_0608.1
I used the following command:
john.exe --format=NT-opencl
--wordlist=\pw-crack\dictionaries\found-ntlm_811m.dic --rules=all
--dupe=0 \pw-crack\pwn_ntlm_88m.rawest
Device 1: NVIDIA GeForce RTX 3060 Ti
Using default input encoding: UTF-8
Loaded 88409988 password hashes with no different salts (NT-opencl [MD4
OpenCL])
Note: Passwords longer than 27 rejected
Note: This format may be a lot faster with --mask acceleration (see
doc/MASK).
Progress is too slow!! trying next table size.
LWS=32 GWS=622592 (19456 blocks)
Press 'q' or Ctrl-C to abort, 'h' for help, almost any other key for status
The computer has a AMD FX-6300 cpu, and 16gb of ram, as well as a nvidia
3060ti.
Running windows 10.
The dictionary I am using has 811 million words and the input I am
trying to crack has 88 million hashes.
The performance from the above command line is about 4000k hashes/second.
The GPU seems to be idle, based on its temperature and voltage.
I suspect the GPU isn't being used, or is being used in some very
inefficient fashion.
I would appreciate any advice on getting better performance.
