hashcat Forum

Does this look too slow for what I'm running? I was expecting higher speed than 7900 H/s on a GTX 1080.

Your speed depends on the number of iterations. You can only achieve the same speed as the benchmark with a hash that has the same number of iterations (or less).

This looks like exactly as the reason why password tools (like Keepass) use the algorithms they use. You should be slow at brute-forcing it, that's the point. I made a Keepass file with 100000 rounds and tried it on my GTX 1070 and also got a slow H/s.

Thank you for that info.
Good to know that it's as expected.
