Have I done something wrong, is this normal, how can I trim it down to like under 5%?

I know you recommend 8 gb ram for nodes and 2 separate ones, but I can’t figure what it’s doing at 30% constantly

Many thanks in advance

Rancher only actually runs in a kubernetes cluster; the single container image is really running an entire cluster inside of it. K8s/its controllers are what they are, and a lot of what they are is relatively tight loops watching for desired vs actual state differences.
