how to increase performance in webi report?

Hi Experts,

I have create report top of universe with 1 query.But inside report i created multiple tabs.Data also less but while executing the report it will take so much time. How should decrease the waiting time.

I followed performance optimization:

1. ALL formula created in Bex itself.

2.Enable Query Stripping

3. Remove auto width and auto height.

4.scheduling the report.

Please tell another some performance tuning.
