Thanks for the data!
It shows that
- IO size is 256KB (which is not a problem in itself)
- The dispatch/complete pattern is
submit IO for range 1
complete IO for range 1
<dd busy, disk idle>
submit IO for range 2
complete IO for range 2
So we have periods that no IO is in flight at all, which leads to
under-utilized disk (which should show up in iostat as <100% disk util)
