Argh! ;-)
Obviously, I cannot read and miscounted the number of digits. I should
have read the seconds instead.
750MB/s is still not the maximum, but totally fine for my purposes here.
Reverting step-by-step all the things I tried yesterday, it looks like
disabling the sync on the zfs volume gave the biggest performance boost,
and I simply overlooked the extra digit when it went from 25MB/s or so to
750MB/s. Sorry for the noise...
