    Hi ,

    For performance of SAP system you need to consider many details before coming to conclusion.As you have sufficient RAM wiht you.I would like to suggest you to have a look into ST03n .Here you can check where exactly you are getting the issue.Either it is OS lvel or SAP level.

    Please check in process if any CPU consuming process other SAP & your DB is running under this.if everything is fine in this regard you can check the load in SAP system if its too high then you may need to add application server for the same.Further you can have a look into SQL queries or particular Tcodes are taking too much resources.

    Kindly have a lok in these points & let us know the details where exactly your bottleneck is ?

    Thanks..

    Hi,

    for getting a clear picture it is very useful that you provide more informations from transaction ST03N. Therefore it would be a good idea to provide performance data.

    Have a look at this link:

    Link: [https://wiki.sdn.sap.com/wiki/display/MaxDB/WorkloadMonitor(ST03orST03N)]

    Here you can find a table with performance data. It shows which process type needs how much response time. Could you be so kind to offer such table from your troubled system?

    Kindly,

    Andreas
