Could you please review this article and ensure that you have correct power management settings both at BIOS and Hypervisor level - vXpress: Performance over Power : Make the right choice.

the bios is set to OS controlled and the hosts are set to high performance. This is the same across all 10 hosts in the cluster and if i move a vm of this one host the contention drops. when i move it back it jumps up again

4. Re: vrops cpu contention
Sunny Dua Sep 26, 2018 8:08 AM (in response to sxnxr)So you see this behavior on one single node of that cluster.. Rest all dont show the contention?
Can you also check the CPU Latency counter in vCenter to see what it is reporting for this VM when it is running on that host.
Also, are these VMs running high Network Throughput or Storage I/O. When I say high, I mean very high :-)
