* Add density (batch pods creation latency and resource) and resource performance tests to `test-e2e-node' built for Linux only ([#30026](https://github.com/kubernetes/kubernetes/pull/30026), [@coufon](https://github.com/coufon))
* Clean up items from moving local cluster setup guides ([#30035](https://github.com/kubernetes/kubernetes/pull/30035), [@pwittrock](https://github.com/pwittrock))

    * The specific behavior of the podGC controller to clean up terminated pods is still governed by the flag, but the podGC's responsibilities have evolved beyond just cleaning up terminated pods.

- Optimized kube-proxy conntrack cleanup logic, reducing the time complexity of deleting stale UDP entries. This significantly improves performance when there are many stale connections to clean up.
