datapump import of compressed dump file slow 11gR2

edited Sep 18, 2013 9:14AM in Database Administration (MOSC) 2 commentsAnswered
I'm experimenting (finally) with datapump exports with compression= all and I'm very happy with the space saved and comparable export time.  Though my testing is revealing an average of 4 times longer to import the data from a compressed file.  The largest sample I've done is approx. 2GB worth of tables.  I'm curious if there's anything I can do to speed up the import from a compressed datapump file.  Besides maybe increasing parallel.

Version is 11.2.0.3

Thanks
