c7t0d0 c7t1d0 is another mirror consisting of two:

Something just popped up. Could the bad stats be influenced by that
this mirror is just created and therefore running in degraded mode?

So therefore I should wait some hours and then try the benchmark once
more?

PS. The intension is to extend the existing pool with this new vdev to
form a raid10 but I will wait with this extending until I am sure the
performs as expected.
