Buffer Paramater Settings

Question

Hi Experts,
In our Development and Production systems , we have been Observed that ,
Lot of Swaps at Program Buffer (PXA) Especially Development systems ..
Some times we were experianced Lot of swaps  Export and Import Buffers also
When we saw at ST02 There was less Space at program buffer and export and Import Buffers .. , and also extended meory use is bit high ..
Could you please let me know that . If system is running with more swaps ( in St02) , How can we avoid this Swaps ?
Is there any formula to fine tune buffer parameters  like program buffer, table buffer , Export/Import ,Roll area,HeapMemory to make the system up and running  with good peformance ?
and also Paging area .........?
Thanks & Regards,
Praveen.

Hi,
Do you take any ofline backups of your developement system ??? if yes then is it weekly or monthly ????if it is weekly need not to worry as the buffer gets reset as system gets recycled.and if theres no offline backups then u need to monitor it atleast a month...then plan to tune the buffer.
Swaps is the number (counter) by which old  objects in the buffer is over written by the new objects from database .
i would suggest to monitor the swaps for a certain period
