Our new Dell SQL server has a single XEON processor. SQL configuration has picked up the system as multiprocessor and when I look at cp performance with Task Manager, it shows two distinct cpu's. Based on the number of issues with parallelism, queries and performance - should I set the processor configurations at single cpu?? Could my queries be taking extra time analyzing whether to use 1 or 2 cpu's?? Any ideas why this happens with a XEON processor?
