Hi Ahmed,
Many thanks for your reply.
Actually, my VM has no limits and reservations set. Is this something related to the physical CPU to vCPU assignment in the ESXi host cluster. why I am saying this is because I am running almost with the 3:1 ratio in a cluster i.e 3 vCPU per processor. But would also like to highlight that all my ESXi hosts CPU performance graph(from DRS cluster resource's view) shows around 50% utilization.
