The import with DataPump of tables into an Oracle11g Release 22.214.171.124 database takes almost 45 minutes, while the same import into Oracle10g Release 10.2.0.4 only take 2 minutes.
The slow Import Data Pump performance problem might also reproduce in other Oracle11g Releases (like: 126.96.36.199) or Oracle12c Release 188.8.131.52.
The problem also reproduces when running an Export Data Pump job from such a release database.
