Low speed

[ds047]

I am running brute-force mask attacks and have noticed that my hash speed varies a lot. I am running this on an Intel CPU. My CPU does not run at its full clock speed either. Is there any suggestions on how I can improve my speed?

What hash are you working on? GPU is recommended for most.

attack speed varies and depends a lot on hash, masklength, given dictionaries or rules

dont use windows taskmanager in conjunction with hashcat to tell the workload (see hashcat output for this), this also applies for gpu

I am not using GPU due to issues with my main PC and servers, thus am running it on laptop as I expect getting a system with GPU up will take a while.

Yes I understand that using something like task manager is inaccurate for certain workloads, however I am using hashcat's output on speed to determine that there is a significant drop in hash speed. I am using CPU-X and htop(I use Ubuntu) to monitor my CPU clock speed and other stats. I have however noted that when using certain instruction sets like AVX and AMX with my code and other software, my CPU runs at a lower clock, I am wondering if the same issue affects hashcat.
