Hi Arun,
The Hit ratio for Prorgam is 99% then it is well and fine. The swaps are more because of the memory pages are been swapped for some program that doesn`t use the frequently used data. Normally the memory size of each page is 8 KB ,so the swapping for the Program until 2000 is well and good.
Check for the program, batch job with the response time which consumes more time and swaps.
But for a single batch job or program if you start changing the parameter value, it would go beyond the limit. Also Check on program with variants having selection criteria with higher limits.
You can even evaluate with the EWA report.
Thanks & Regards,
Ahamed.
