SAP system performance problems

[Former Member]

Hello,

I´m trying to understand something about how and what can be done to improve our SAP system performance.

First of all this is a SAP ERP system that is installed in a windows server 2003 on a MS SQL Server database (in a cluster - cluster administration). We noticed that the performance of this SAP system is not the better and some users told us that some actions during the transactions are slow. The two servers (two cluster nodes) have a lot of RAM memory and also page file so I believe this problems are not related with this particulary things.

Can you told/teach me how can I check and measure if the system are with some problems!? Which transactions I must check to make this analysis and how can I correct/improve this situation?

Can you tell me please some tips regarding this type of problems?

Thank you,

Hi Samid,

From the screen shot of ST02, its clear that the export/import buffer overflow has occured and high number of swaps has occured. High number of swaps will always a major concern in performance point of view.

Please refer the below notes to improve the export/import buffer

373986 - Overflow of the export/import buffer

702728 - Profile parameters for export/import buffer instances

649613 - Export/import buffer SWAPS

Thank you Nikhill, I completely miss the Export/Import Buffer hit ratio. It is fine if this buffer has Hit Ratio % above 80%, but in this case the Hit Ratio is below 80% and the buffer size should be raised.

Anyway, in this case I think that the system performance issue is not related with a wrong seize on the buffers.

Best regards.
