impdp with PARALLEL not working

Question

I would like to load Oracle dump files in parallel. I have 23 cores on my machine. All the dump files were created using expdp.

To do so, I ran this command:

impdp $RMS_SCHEMA/amadeus@$TWO_TASK directory=RMS_DUMP_DIR2 dumpfile=Auto_SK_LAD_MIG04.%U.dmp logfile=import.log PARALLEL=33

Unfortunately, the import is not any faster.

Here's what I get when I show the status of my datapump_job

Import> status
