Orr, Steve, I am using Xeon MP as well on my DELL 6650 , and i have two nodes. I will patch my database next evening and later turn on the logical cpu feature on one node and leave the other node as it is. I will compare the cpu load/application responce time change and give you the feedback. Good luck
