Do you have any time savings of your use of SETOBJACC?

I created a 400,000,000 record test file.
Created a simple test program, read the file, beginning to end.
14 minutes to read all 400,000,000 million records.

SETOBJACC OBJ(PAULS/CCEKCPP) OBJTYPE(*FILE) POOL(*SHRPOOL1)
46877104K of CCEKCPP brought to pool with 25441484K unused.

Reran the same test program.
11 minutes to read 400,000,000 million records.

SETOBJACC OBJ(PAULS/CCEKCPP) OBJTYPE(*FILE) POOL(*PURGE)
Member CCEKCPP purged from main storage.


The best comparison is to read the file twice (getting times for
each read-through) before comparing to a read-through with SETOBJACC.
