Ideally, a TiDB cluster should always be efficient and problem-free. There shouldn't be any jitters (either in the cluster or on disk), and no hotspots, slow queries, or network fluctuations. For external reasons, application traffic may surge and increase the pressure on the cluster. However, reality is often unsatisfactory.
