We are running rancher 2.14.3 and are experiencing massive issues with the UI when doing any kind of changes to fleet mechanics via gitops, or to cluster management via terraform. The UI becomes fully unresponsive. The clusters work fine and eventually the UI will come back alive but we are wondering what the issue could be. Our 3 Rancher nodes handle 6 downstream cluster which are all without actuall workload because we want to migrate to rancher. Each rancher node has 32G of memory and 16cores and we do not see these resources as the bottleneck. Is anyone facing a similar issue with the UI performance being bad during changes to the rancher mechanics?

Are you by any chance restarting the rancher containers or pods? In our Kubernetes environment that has caused some latency problems for our clients.

afaik we don't. I'm not sure how to troubleshoot the issuse. We thought of increasing nodes and manually pinning pods to certain nodes to make sure they are not hogging resources, but I do not believe this will help. Resources overall are not very much used.
