Hi,

We have an esx 6 server with 2 x 8 core cpu's and a total of 32 logical cores.

On this server we have 4 vm's. See below for the number of vcpu for each.

VM1: 1 vcpu (linux)
VM2: 1 vcpu (windows server 2012 R2)
VM3: 8 vcpu (windows server 2012 R2)
VM4: 10 vcpu (windows server 2012 R2)

How is it possible that sometimes we experience cpu ready times of 4% to 10%?

That shouldn't be the case for this amount of available logical cpu's and this amount of provisioned CPU's..

Any help is very welcome.

Thanks.
