I've been having io performance issues with two new servers, and while testing I noticed that when I had Hyper-v turned off at boot using "bcdedit /set hypervisorlaunchtype off" that my disk tests showed a large improvement. When hypervisor is turned on at boot, performance drops even with no VMs running, and "HV Host Service", "VMMS", and "vmcompute" services stopped. Is this normal, or does anyone have an idea why it's happening? Thanks!
