When hashcat starts up there is a list of optimizers that show what can be applied in the current attack. As you change things about the attack, some of those may become unavailable and the speed differences can be severe. For both MD5 and NTLM there is a major optimizer related to singal target attacks. Are you attacking multiple hashes? That will reduce the apparent speed significantly(sometimes as much as 60%) if so, though this isn't to say that attacking multiple hashes is bad or that the speed you are seeing is bad necessarily.
Ah, thank you very much. I just tried doing one single hash, and the speed increased from 20GH/s to 60GH/s per GPU. Closer to the 70GH/s for NTLM that I was expecting. I didn't realize that multiple hashes had that big of an impact on speed. Out of curiosity, is there a hash type that isn't impacted by processing multiple hashes at once?
Could you kindly elaborate on the other factors you mentioned that might influence performance? Furthermore, I am curious about any additional adjustments I might consider for my parameters, such as the potential deactivation of hwmon.
Once again, I appreciate the help.
