### Bug or Regression

- An inefficient lock in EndpointSlice controller metrics cache has been reworked. Network programming latency may be significantly reduced in certain scenarios, especially in clusters with a large number of Services. ([#107167](https://github.com/kubernetes/kubernetes/pull/107167), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

- Resolves a performance regression in default 1.31+ configurations, related to the ConsistentListFromCache feature, where rapid create / update API requests across different namespaces encounter increased latency. ([#130136](https://github.com/kubernetes/kubernetes/pull/130136), [@AwesomePatrol](https://github.com/AwesomePatrol)) [SIG API Machinery]
- The following roles have had `Watch` added to them (prefixed with `system:controller:`):
  

	* Add metrics to all major gce operations {latency, errors} ([#44510](https://github.com/kubernetes/kubernetes/pull/44510), [@bowei](https://github.com/bowei))

	    * The new metrics are:

	    * cloudprovider_gce_api_request_duration_seconds{request, region, zone}

## Changes by Kind

### API Change

- Revert regression that prevented client-go latency metrics to be reported with a template URL to avoid label cardinality. ([#112056](https://github.com/kubernetes/kubernetes/pull/112056), [@aanm](https://github.com/aanm)) [SIG API Machinery]

### Feature

- Fix missing cadvisor machine metrics. ([#97006](https://github.com/kubernetes/kubernetes/pull/97006), [@lingsamuel](https://github.com/lingsamuel)) [SIG Node]
- Fix: azure file latency issue for metadata-heavy workloads ([#97082](https://github.com/kubernetes/kubernetes/pull/97082), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]

* kubectl get did not correctly count the number of binaryData keys when listing config...

  reclaimed.
  - This feature prevents the node and scheduler from oversubscribing resources
    that are still being used by a pod in the process of being cleaned up.
  - This feature can result in increase of Pod Deletion latency especially if the
    pod has a large filesystem footprint.

### RBAC

The CustomCFSQuotaPeriod alpha feature enables node administrators to change the default period used to enforce CFS quota on a node.  This can improve performance for some workloads that experience latency while using CFS quota with the default measurement period.  Finally, the SIG continues to focus on improving reliability by fixing bugs while working out design and implementation of future features.

### SIG-OpenStack

beta in the 1.10 release.  First, [CPU Manager](https://kubernetes.io/docs/tasks/administer-cluster/cpu-management-policies/), which allows users to request exclusive CPU cores.  This helps performance in a variety of use-cases, including network latency sensitive applications, as well as applications that benefit from CPU cache residency.  Next, [Huge Pages](https://kubernetes.io/docs/tasks/manage-hugepages/scheduling-hugepages/), which allows pods to consume either 2Mi or 1Gi Huge Pages.  This benefits...
