Kubernetes is a complex tool. As is the case with most complex tools, getting optimal performance out of Kubernetes can be tricky. Most Kubernetes distributions don’t come fine-tuned to maximize performance (and even if they did, it’s likely that they would not be tweaked in a way that is optimal for your environment). With that
