Symptoms

Datapump export  is taking more than the double time after a database upgrade from 10.2.0.4 to 11.2.0.3

In our example, one table with a LOB column takes more than 18 hours. The rest of the objects are exported within 30 mins.
Here is the current size of the table with a blob column based on the output of the export..

. . exported "TEST"."TEST01" 408.8 GB 173268 rows

Changes

 Database was upgraded from 10.2.0.4.0 to 11.2.0.3.0
