Kubernetes performance is heavily influenced by the underlying hardware. Running a database on a Kubernetes cluster should deliver similar performance, with less than a 1% difference when compared to running it on standalone hardware. However, Kubernetes does introduce additional layers, particularly in storage and networking.
