I'll also add that the people that want to do the partitioning for performance are making a big mistake. Partitioning doesn't improve performance in almost every case. Proper indexing and query design does. You've already found that out in the performance improvements you've made.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

With 19GB in tblCall, I'll say that it's starting to get to the point where partitioning could be of some help for reduction in backup time but only if you can make the old years "read only".

With that in mind, let me ask the question again... are you saying that they update CDRs that were made in 2014 even at this late date?
