Hi, 

Does anyone know the reason for VM resizing time to increase faster if you continuously increase CPU or DISK resources by +1 (e.g. 1-2, 2-3, 3-4, 4-5). Whereas, when you increase from 1 to any of +1/+2/+3/+4…..+n (e.g. 1-2, 1,3, 1-4, 1-5), the VM resize time still increases at each step, but it takes less time in comparison to the former method. Can anyone give an explanation for this? 

Thanks!
