Hi,
I have an issue with unjustified speed drops. Usually for WPA2 I have nice speeds, around 176 kH/s.
I wanted to try hybrid dictonary + 3 digits:
Which results in nice speeds:
Now by just changing the order (?d?d?d + dictionary) I get 5 times slower speed:
Few facts:
- the speed is almost constant for both cases, testes that a couple of times
- same input is used for both cases, however changing dict and hccap file changes nothing at all
- the gpu utilization is ~93% not ~99% as usual (per MSI afterburner) for the second, slower variant - indicating some issues with feeding the gpu with data
- running windows + cudahashcat 1.31 + hashcatGUI 0.44
- newest drivers
- the wordlist is on SSHD
- GPU temp is at relaxed 60 C
- neither the SSHD nor CPU/memory seem to be bothered in anyway
My humble question:
Why shift from dict+mask to mask+dict caused such a decrease in speed?
