Hello Mark, Just +$0.02 to Hugh's description. Some applications may explicitly parallelize their execution by creating asynchronous queues of small queries instead of running single big query. E.g., multiple cores are useful for multi-thread loading of large RDF files. Nevertheless this feature is for Virtuoso/PL routines and it does not affect running any single SQL SELECT statement.
