Expedite impdp process

Question

Hi All,
We are importing Oracle Application 11i database from AIX 5.3 to RHEL5, Database version 10.2.0.4
Following MetaLink note: 10g Release 2 Export/Import Process for Oracle Applications Release 11i [ID 362205.1]
Having a database size of 132.99 GB we generated the export dump file of size 32 GB from the source. Import process took around 36 hours
Our Linux machine has 2 CPU’s with 8 cores
How to expedite the import process??
Kindly suggest
Thanks
SK

Hi,
I also had the same issue with impdp and have raise a service request with Oracle support. When I ran an strace on the process, i am getting these messages:

I also on OEL 5.4
I tried altering semaphore settings to the following value, but did not help much..
kernel.sem = 5010 641280 5010 128
