why Datapump is faster than traditional export and import..

The Data Pump is a server based utility vs. the traditional
Export / Import which are client based utilities. The
Oracle Data Pump is not compatible with the Export / Import
functionality.

The Oracle Data Pump can also use NETWORK_LINK
functionality to move data and metadata from a remote
database without a dumpfile using the network technology
between the two databases.

Answer / rizwan

In traditional datapump exp/imp utility we can not stop the job when it's processing.
