Hello, I like to have some idea about services separations, CPU and RAM or any other consideration if we like to optimize dashboard experience.
I just like to have high level recommandation because it's friday 
and I don't like to spend to much time about write my reel case.
But let me give you some more detail.
Right now, we use Dashboard design with BO 4.0 SP5, we have about 25 big dashboard in production with problably 25 users using it everyday. 90% of dashboard used web service call (webi cache content) and 10% direct query call. We are in the process to find where come from slow down when append but at high level, I like to have some recommandation.
How can we have more stable and fastened process of web service ?
How can we grow our infrastructure if we like to have more power in general for dashbard ? The sizing guide does help much.
What else is important ?
Hope my message is not too short !
