STAD Report generation takes too Much time

Dear Experts,

In our Production system if we execute the STAD report for10 minutes to get the business transaction data for a single user or multiple users. Its taking too much time upto 500 sec sometimes throwing DUMP due to time out.

We have the issue from the begin itself.

What are the checks needs to done and how to fix the issue ?

Is that possible to schedule the same in Background to get the output and how ?

System Info:

ECC6.0 EHP4, Kernel Release 701 Support Pck - 55.

Windows MSCS Clustering.

SAPOSCOL on both instance.

Thanks,

Jai
