It all depends on your application if your application are single threaded I doubt you would see much difference in performance from any of these systems. You first really need to understand the types of applications you plan to support. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Allen, Jack Sent: Monday, February 25, 2008 4:42 PM To: General Red Hat Linux discussion list Subject: Dual-Core and Quad-Core performance question Hello: Can anyone point me to some information about the performance differences of say the following systems. A) 4 Single-Core CPUs running at 3.0GHz B) 2 Dual-Core CPUs running at 3.0GHz C) 1 Quad-Core CPU running at 3.0GHz Everything else being the same, that is 4GB of memory, disk, etc... The reason I ask, is I have been told that a Dual-Core System will only give about a 25% performance improvement over 1 Single-Core system. That is not it is not twice as fast. ---- Thanks: Jack Allen -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=subscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
