    Performance DB 11g better than 12c in Exadata X5.


      Hello ...

      We're testing a migration from DB 11g to 12c, Exadata X5, and 11g performance is a lot better. The memory configuration, IORM, in the 2 instances (11g and 12c) are the same.

      In 12c it's using much more CPU in the processes, and in the 11g uses CPU and IO user, which leaves more performative.

      Is there any recommendation for parameters or other to improve performance on 12c and leave at least the same?
