Hi… The “balance” line actually uses the scale way over on the right-hand side (double Y-axis).
I.e., it’s reading 5 milliseconds, which actually means zero (due to an odd quirk in the dashboard):
The utilization (the green part) is pinned right up to the yellow dashed line (“baseline”), which means that you really are being throttled. The red line is how much more your system really wants, loosely speaking…
Personally, I would try this out on a single-CPU performance-class Machine, even if that’s not ultimately what you want to deploy. That would prevent the multi-core and throttling aspects from muddling things—and give you a better idea of what the real minimum actually is…
Hope this helps a little!
