Multi CPU in Hashcat

[ice2001]

My server has 4 Processor .
see the result of this command : less /proc/cpuinfo :

and i use 30 thread but the speed of my cracking is slow (19 m/s) , i think that hashcat just use one of the Processor . i want use the 4 processor what am i going to do ?
Thanks .

try -n 4 instead

to be more specific, you have 1 processor with 4 cores and you are trying to push 26 extra threads through 4 cores that are already going to be close to max utilization.

[ice2001]

yes its max utilization , but its not mean that i have a processor with 4 cores , see "cpu cores : 4" in the result of "less /proc/cpuinfo" , and -n 4 is so slow (10 m/s)

[atom]

try gpu based cracking, its much faster

You have a single processor with 4 cores.

@atom : yeah gpu based is too fast , but my server and my system dosent have a nice graphic .

@radix : yes its true . Thanks
