Remarks
=======

* Mean read latencies cannot be modulated with throttling.
* Mean write latencies cannot be modulated with throttling.
* bandwidth: Isolatable memory size is 15.84% < supportable, sizing may be difficult.
* isolated-bandwidth: Isolatable memory size is 15.84% < supportable, sizing may be difficult.
