I can neither show zpool history nor zdb -v as the both are too large.
The first one is around 13000 lines long and the other one more than a
million lines and rising.
@Uncle Stoatwarbler: thank you for the tip, yet another xtop version I
did not know about and will definitely be put to my tools list.
@Brian Behlendorf: How can I take a look at zfs_scan_idle and how
would I be able to modify it?

Many thanks to all your help and suggestions ;)

cheers,
Nils
