Report performance while creating report on BEx

All all!

I am creating a report on BOE 4.0 on top of BEx connection as a source. I have developed reports on top of universe in the past and i know that if we keep calculations on reporting end it hampers the report performance. Is this the same case with BEx? if we are following the best practices is it ok to say that we should keep all heavy calculations/ aggregation on BEx or backend for better report performance.

Can you guys please provide your opinion based on your experiance and knowledge. Any feedbacks will help! Thanks.

    As per my experience, I would say it is better to have your calculations at Bex or backend side for better performance.

    Definitely best-practice to delegate a maximum of CKF to the Cube where possilble, put RKF in the BEx query, and Filters too.

    also, add Default Values to your Variables (this will speed up generation of the bics transient universe)

    also, since Patch2.10, we are seeing some significant performance improvements reducing 'document initialization' and 'time to prompts' by up to 50% (step such as these often took 1.5 minutes, even on sized systems)

    Also, make sure you have BW corrections like this implemented: 1593802 Performance optimization when loading query views

    In the BusinessObjects landscape - especially with BI 4.0 - it's all about Sizing and Tuning . Here is your bible the 'sizing companion' guide :

    Pay particular attention to BICSChunkSize registry settings

    Also, the -Xmx JVM Heap Size for the Adaptive Processing Server that is running the DSL_Bridge service.
