Hello,
i have exactly the same problem with Win10 CPU Performance.
I have vSphere 6.5U1 on HP G8 BL460c Blade Server.
Problematic VM is Win10, 6Gb RAM, 3x1vCPU.
In the same cluster i have Win 8.1. which is OK.
I found your thread on communities and i can see that you had same problem in August last year.
Please, did you solve the problem and if yes...How?
Thank you very very much for answer:-)
Have a nice day.
