In the SQL Server 2012 execution plan we can see better the true thread reservations for a query and not just information on the maximum degree of parallelism and row distribution across parallel threads; thanks to the new parallel thread usage information.
SQL Server 2008 introduced a new feature, Management Data Warehouse (MDW), which allows users to collect metrics on their servers over time to aid in performance troubleshooting.

In fact, removing MDW is not supported; in SQL Server 2012, though, a new system stored procedure was added to make this process easier. The problem is that this stored procedure (as well as several of the workarounds I've seen published) can leave several objects behind.

We can use one of the rules-of-thumb to choose what should be roughly the best number of files, but how then do you check to see whether you've got it right for your data and workload?
