[madhancog]

HI,
  We have created the cube from publishing the package in 8.3 we have a lot of performance problem.can i know whether we can use IQD file as source and create the cube so that we can improve the performance.
let me know the best way to fine tune the cube.it is taking much time more than 45 min for 60mb cube.

Thanks in advance

Did you check the (Cube build process) Log file and did you identify the step / the steps which are time-consuming?
