I will propose a patch with a default bb.debug, and always have the
verbose on dnf. Let's see how it affects the performance. I cannot
test this in a docker container because of the problems described
below:

In the mean time I found what was happening with my slow do_rootfs. I
was running bitbake with RPM packaging in a docker instance. It seems
there is a problem with RPM/dnf in bitbake where it is extremely slow
inside a docker container (1 file per second). After changing to IPK
packages everything went smoothly.

Others have had the same problem[1]. I will later report this to
openembedded mailing list as this effectively makes RPM unusable in a
container. I will also provide a Dockerfile to reproduce this problem.

No need to report. We have already fixed this and reported upstream:
