I used Export/Import Dump utility to achieve it as I need to extract only a subset of data from the production.
The Export was fine but the Import had huge delays.
The reason being archivelogs during the import process which cannot skip the redo. So , for all the objects that were created the system was generating redo which turned out to generate archivelogs.
IMPDP does not have an option to switch off archivelogs.
Study in metalink found that there is an Enhancement Request 4568451 for the same which will be available from release 1 version of the database as a patch.
At present I am switching off archival at the database level to achieve the speed in importing.
