I found in that thread:

I had the same problem. A temporary fix is to set "Numa.RebalanceEnable" to 0
esxi-host configuration, Software, Advanced Settings, Numa, Numa.RebalanceEnable = 0
Supermicro Opteron 61xx and 62xx hosts.
When I did this the cpu load balanced evenly between the cores and the ready times dropped to 0.XX as was expected.
did the same, result in screenshot, pretty better isnt it ?
