That does not sound right the debian image should be using ALL 8 cores, are you able to give us the output of lscpu nproc and look at htop?

Okay that is wierd, I am just now getting back to this board and in fact yes all 8 cores are reporting and working fine. And now I can’t even remember what the command was I used in the op, but both lscpu and nproc report 8.
