Did a quick test on a 3-node cluster with 4 vCPUs, 8GB RAM each. Bare metal, Ubuntu 22.04.
kubeadm (v1.28) took 4 minutes 12 seconds from init to a ready control plane.
RKE2 (v1.28) took 6 minutes 48 seconds.
That's a big difference. RKE2 is supposed to be the "simplified" distribution. What's taking the extra time? Is it all the extra bundled components?
Looking for the cheapest, fastest path to a working cluster. Not interested in bells and whistles I won't use. Are these bundled extras in RKE2 actually worth the slower startup and likely more resource overhead?
