Predictable Processor Performance

Regarding this, will the utilization limits be tracked on a per core or per instance basis?

If it is per instance, it seems to reason that since burst utilization will be allowed, a shared-8x instance could consume a sustained single core workload of 50% of a core if neighbors allow. In effect, it would have 20% less sustained single core performance of a performance-1x even though you have access to 8 virtual cores, with the main limitation being low priority compared to neighbors.

My understanding is that it is tracked per instance instead of per core (especially as the balance metric doesn’t have any CPU identifiers in the attributes), so yes theoretically you could use shared-8x with a single core app and sustain a load of 50%.
