Is there any feature for bench-marking ones DB servers/ procedures for comparison later?
What kind of benchmark did you have in mind? There are some pretty cool reports you can run to see historical performance.
Here's one for SPROCs: DPA Report on Stored Proc Impacts
However, we're discussing better ways to aggregate the data. Would you be open for a call so we can get a better idea of what a good benchmark would look like for you/how it would be used?
If yes, I can reach out privately to you.
