Because the MaxDegreeOfParallelism property represents the maximum degree of parallelism, the dataflow block might execute with a lesser degree of parallelism than you specify. The dataflow block can use a lesser degree of parallelism to meet its functional requirements or to account for a lack of...
The default value of 0 uses all available processors. Setmax degree of parallelismto 1 to suppress parallel plan generation. Set the value to a number greater than 1 to restrict the maximum number of processors used by a single parallel query execution. If a value greater than the number of...
There are plenty of references for tuning MAXDOP to allow queries to run at their best while reducing the overhead of the parallelism. You have all seen the references for capping MAXDOP at 8, or number of schedulers of the NUMA node if smaller, or …. The fact is, these are...

Set sp_configure ‘max degree of parallelism’, 80 -- Warning this applies to any query 3. Create resource pool/workload group and set MAXDOP=80 and assign only the index build connection to it using a resource governor classifier. </blockquote>...
Before choosing to execute the query using serial or a parallel plan, the SQL Server Database Engine will check if the SQL Server instance is running on a server that has more than one processor. The Maximum Degree of Parallelism (MAXDOP) is configured to allow parallel plans where a MAXDOP...

Use this tab to specify your max degree of parallelism. This setting determines how many processors a single statement can use during execution. The recommended value is automatically calculated during installation. This was a post-installation task by database administrators of production instances, ...
