I've copied/cloned a database to another unix filesystem on the SAME
server.  I did it by copying datafiles over then reconstruct control
files.  Now the user is complaining the cloned database is
significantly slower than original database!  We have a complicated
query it takes 1 hour in original db but 3 hours on cloned database.

The init.ora parameters are exactly the same except database name,
location of archive, control files...  The nature of filesystem is
exactly the same.  And they are in the same Sun Solaris server.  The
CPU is pretty much at the same state when we did the comparison test.

Any idea?  Will cost base stat copy over after cloning?
