I challenge anyone to, in a double-blind test, notice any difference between 2 and 4 cores for a regular office/desktop workload. (no compilations, video editing, CAD/CAM, Mathematica, raytracing etc.)
I do most of my work in Virtual machines. (Vmware). Multiple different Linux distros and Windows versions are needed for my testing. I can adjust the number of cores on a vm and see the difference immediately, whether the VM os competing with other vms or simply running alone. It makes a huge difference adding a second core. Not much difference going to 4. The more windows you have open the better it all works, until you start running into IO bottlenecks. (With Windows, you get less per additional core than with Linux). I use to have lab full of identical machines for this, and saw the same results there. We manufactured machines for a long time, and had many for testing. However, anytime there are multiple physical machines involved you can never be perfectly positive things are identical, as simple things like disk fragmentation can play a role in masking actual performance. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
