DF XI 3.0 Performance Tuning

Hi,

I have installed DF XI 3.0 on a 64 bit server with the 64 bit install. There is a huge performance difference between the 32 bit XI R2 DF versus the DF XI 3.0 64 bit version - where the 64 bit XI 3.0 is much slower compared to XI R2.

Webi reports that use the new DF XI 3.0 run atleast 500 % slower than the R2 based queries.

I tired increasing the Javaservicedebug for Repository, Designer to 1 GB of RAM - but that hasn't made any difference to the performance.

Are there any known issues with Performance on XI 3.0? Any tuning on parameters can help improve the gap?

Thanks,

Siva.
