12.2.0.1

I've recently had a case at a client where it was questioned why a particular application was seemingly not making full use of the available I/O capabilities - in comparison to other databases / applications using similar storage.

Basically it ended up in a kind of finger pointing between the application vendor and the IT DBA / storage admins, one side saying that the infrastructure used offers insufficient I/O capabilities (since the most important application tasks where dominated by I/O waits in the database), and the other side saying that the application doesn't make use of the I/O capabilities offered - compared to other databases / applications that showed a significantly higher IOPS rate and/or I/O throughput using the same kind of storage.
