Bug Description

Binary package hint: dkms

By dkms calling itself to get information about dkms module status at each kernel module during uninstall, a big amount of time is wasted, since at looping on the kernel modules of a dkms module, the status of the latter will not change.

Putting the same outside the loop speeds up execution for the same by factor 60.

This is actually fixed in master, albeit a bit differently. There was a huge rewrite that happened by Victor Lowther to optimize for bash better.
