Dear All, could you help me solve my problem, please? I have vmware virtual machine Win srv 2003 R2 with 2 vCPUs. Everything was ok until we installed new aplication and CPUs are so busy now. Problem is when I want use more than 2 vCPUs. I add more 2 vCPUs so Virtual Machine has 4 vCPUs, Windows system Device Manager has 4 CPUs but Windows Task Manager has ONLY 2 CPUs. When system is busy Windows CPUs usage is on 100% and vmware performance VM is only on 50%. Do you know what I must do, please? Thank you very much
