Max Degree of Parallelism
The max degree of parallelism (MAXDOP) configuration option limits how many processors can be used during the execution of a query. Having the setting too low can limit SQL Server's ability to benefit from running queries over multiple processors, but having it set too high can cause problems with CPU contention. Other factors include MAXDOP set at a database level, resource governors, and the MAXDOP query hint.
