It must be due to
https://gitlab.com/man-db/man-db/-/blob/1e5462f3fd9bfd8cf496e32e23842018b67f9b91/NEWS.md#L233. It
takes 10 seconds on -current with mandb 2.12.1 but it indeed took 6
minutes on -stable in the VirtulBox with mandb 2.9.4. After I compiled
it from source it took 20 seconds on -stable too.
