The Data Pump Export and Import utilities are designed especially for very large databases.

(Performance of metadata extraction and database object creation in Data Pump Export and Import remains essentially equivalent to that of the original Export and Import utilities.)
Topics that will help you to understand why Data Pump performance is better and that also suggest specific steps you can take to enhance performance of Data Pump export and import operations are:
