Guests benefit by having more than one cpu. If more than one guest is competing for CPU, they load balance. So generally speaking I think it's a good idea to give all of your CPU's to all of your guests. Well... n-1 If I *actually* give all the cpu's to all the guests, there doesn't seem to be enough leftover for the host to figure out the load balancing very well. So I generally assign n-1 to each guest. The big question is hyperthreading. If you have 4 cores that virtually look like 8, how do you count that? Do you think you have 4? Or 8? I've never come up with an answer to this question, so I take the conservative approach. ------------------------------------------------------------------------------ Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.
