Re: Running/Licensing Hyperthreaded Intel Pentium4 Xeon CPU's on Linu

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
