By default, Cilium will use CRDs for synchronizing agent state. This can cause performance problems on larger clusters. As of kOps 1.18, kOps can manage an etcd cluster using etcd-manager dedicated for cilium agent state sync. The [Cilium docs](https://docs.cilium.io/en/stable/gettingstarted/k8s-install-external-etcd/) contains recommendations for when this must be enabled.
