    Hi,

    1. you can "suppress unassigned nodes" in RSH1

    2. you can enable Query Stripping in webi query panel and webi document properties

    3. you can enable BICSLOVChunking registry settings

    --> Note 1581323 - BI 4.0 Web Intelligence very slow performance when using BICS

    4. modify the WebiParamMaxLovSize settings

    --> Note 1671774 - "OutOfMemory exception" and poor performance when accessing large LOV's in WebIntelligence (using Desktop client or Launchpad) using BICS to connect to BEx query

    5. you should implement all the latest BW correction from the BI-RA-BICS component, such as BICS Note 1593802 Performance optimization when loading query views

    6. You should use the latest available Patch2.12 (optimizations since 2.10 are very good)

    7. you should answer as many Filters (Bex variables) as possible during runtime.

    Regards,

    H

    p.s. after these steps, the rest is down to Document, Query, and Datamodel design.
