RKE2 less performant than RKE1?

Hi,

In the Rancher installation requirements: Rancher Docs: Installation Requirements

On the one hand, I see that Rancher installed on an RKE Kubernetes cluster can support up to 200 clusters and 20000 nodes.

On the other hand, I see that Rancher installed on an RKE2 Kubernetes cluster can support up to 15 clusters and 200 nodes.

Why this limitation for RKE2? I thought it was the “new-gen” Kubernetes distribution from Rancher, so why are bigger workloads supported for RKE, but not RKE2?
