> If you care about perf you would pin the kubelet
Wrong. I wouldn't use kubelet at all. Kubernetes and good performance are not compatible. The goal of Kubernetes is to make it easier to deploy Web sites. Web is a very popular technology, so Kubernetes was adopted in many places where it's irrelevant / harmful because Web developers are plentiful and will help to power through the nonsense of this program. It's there because it makes trivial things even easier for less qualified personnel. It's not meant as a way to make things go faster, or to use less memory, or to use less persistent storage, or less network etc... it's the wheelchair of ops, not a highly-optimized professional-grade equipment.
