Try ...statistics=none

Then analyze after the import.

Subject: impdp import schema very slow ????

We have ORACLE 10.2.0.2 on LINUX server. I saw ORACLE document say "expdp/IMPDP" performance a lot better than "exp/imp".

I have been tried expdp/impdp schema and found "impdp" performace very slow (at least two to three times long than "imp"). When we do "impdp" it will stay on "Processing object type
SCHEMA_EXPORT/TABLE/STATISTICS/TABLE_STATISTICS" for 20 -30 minutes.

Does anyone know why?

Thanks.
