Is it normal to import a dump of 40M data into a clean schema for 17 minutes ?
The command we use is
impdp user/password@ORADB DIRECTORY=EXPORTDP DUMPFILE=TEST.DUMP LOGFILE=TEST1.log SCHEMAS=SCHONE REMAP_SCHEMA=SCHONE:SCHTWO EXCLUDE=STATISTICS
No. of tables : 1300
Anyway to tune ?

Do any of the tables have a LONG datatype?
Is the database on the same server? Importing across is network is very slow.

The schema do not have the LONG datatype. The dump file is on the same server.
Michel Cadot:
Any trace/log file that I could check for the bottleneck of the impdp ? I also try to enlarge the sga but it doesn't help.
Besides, how long would it take normally for importing 40M schema with data ?
