Hi, Aron I used dkms 2.6.1-4 from buster.
Hmm. Yes, configure part is slow, and unfortunately serial due how the autoconf works in general. Maybe it was a configure indeed, not the actual compilation, I didn't check full command lines in `top` to see what was being actually compiled by `cc`. I think you might be right then.
