What is the total size of the SGA (query V$SGA) of each database?
How much is that compared to the total memory in the machine?
Is there sufficient memory remaining for the operating system and file
system cache?
Are you sure the response time is not slower in the original db too (when
both databases are up and running)?

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