<p>I want to increase the performance of the Kubernetes scheduler by changing the weight of the priorities (or eliminate some priorities), I want to know how I can change the weight of the priorities in the scheduler? and what is a default scoring strategy used by kubernetes?</p>

<p>I think this file has defined the default policies: <a href="https://github.com/kubernetes/kubernetes/blob/master/pkg/scheduler/algorithmprovider/defaults/defaults.go" rel="nofollow noreferrer">github source</a>. You can modify the default policies and weights by passing a policy-config file (<a href="https://github.com/kubernetes/kubernetes/blob/release-1.5/examples/scheduler-policy-config.json" rel="nofollow noreferrer">example</a>) with <code>--policy-config-file</code> option to kube-scheduler.</p>
