Subject: very low cpu usage when cracking one password
I am running a recent version of john, using descript on a single
unknown password.
I have a 64 core amd epyc processor.
John is running, but it seems to be using only 1 thread.
My cpu usage is between 1 and 3 percent.
Is there any way to use more threads when I have only 1 psssword to crack?
thanks,
jeff
