vMotion spike host CPU latency/ready to 100% (6.5)

Looking through vSphere metrics I see that vMotions are causing host CPU latency/ready to spike to 100%.   Is this normal?   Is there anyway to limit the impact?

Thanks,

Hi,

How many VMs are you moving?

Are these VMs configured with high resources (compared to the host)?

Single VM,  underutilized 36 core Broadwell.

Any VM yeilds same results.   Some might "only peg CPU latency/ready to 60%.
