SQL server 2000 to 2005

but we have face the problem of performance when execute Z reports.

please suggest me how to improve the performance.

I have set the parameter according note 88416.

Hi

If your having disk space you can increase the Swap from the physical memory to 2 or 3 time, after that you can check the buffer setting in T code ST02 if anything shows red color (Swaps tab) increase the value form current value to 10 to 20 %

You can check the Z reports in the ABAP trace in ST12
