Large "steal time" inside VMs but host CPU is not overloaded
-
@lovvel from a software standpoint, this is a 16 cores CPUs and AFAICT, Xen doesn't account for these slight differences between cores.
As to be fair, it's not really easy to know in practice if a 3D-VCache core will be faster than a non-3D-VCache one for a specific case.

Thanks for your feedback, @TeddyAstie and @gecant . From your answers and the discussion in Non-server CPU compatibility - Ryzen and Intel I conclude, that the benefits of the 8 V-cache cores vs. the 8 turbo cores are just irrelevant. For XEN they are transparent and not really different in terms of performance. Hence, in a typical server environment we just let XEN randomly choose the cores and don't think about different "performance cores" that COULD be faster in specific applications like games.
