I have a chart that shows the cpu usage has exceeded the total cpu utilization on the system, up to 13320 MHz, how is this possible?<br /> <p /> Addin in all the physical cores and hyperthread it should add up to 12 Ghz.<br /> <p /> 3.) I attempted to determine if it is a percentage of the total, on another machine I have these numbers:<br /> <p /> <p /> <p /> <p /> <p /> <p /> <p /> <p /> <p /> Machine 1:<br /> <p /> 4200/ 6000 = .7<br /> <p /> Machine 2:<br /> <p /> 37145/39888 = .93<br /> <p /> (Resource Allocation) / System Resource Allocation = % available for vm use.<br /> <p /> <p /> <p /> <p /> <p /> <p /> <p /> <p /> <p /> I am amazed at the performace improvement of esxi 4. <br /> <p /> We migrated 2 vmware 1.0 servers each running 6 virtual machines to one esxi server running 4 virtual machines. We get equal performance with the 1/2 the hardware and 1/3 the number of virtual machines.
