If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Add scheduler benchmark tests for PodAntiAffinity rules **What this PR does / why we need it**: This adds a benchmark test that measures the scheduling latency of pods with PodAntiAffinity rules where topologyKey=kubernetes.io/hostname. Additionally, this PR imposes a minimum `b.N` value to make the test results more meaningful. The benchmark is needed to validate any performance improvements made for #54189. Command used to invoke: ```sh make test-integration WHAT=./test/integration/scheduler_perf KUBE_TEST_ARGS="-run=xxxx -bench=." ``` Sample output: ``` pkg: k8s.io/kubernetes/test/integration/scheduler_perf BenchmarkScheduling/100Nodes/0Pods-40 100 36316838 ns/op BenchmarkScheduling/100Nodes/1000Pods-40 100 69460001 ns/op BenchmarkScheduling/1000Nodes/0Pods-40 100 193755560 ns/op BenchmarkScheduling/1000Nodes/1000Pods-40 100 343451472 ns/op BenchmarkSchedulingAntiAffinity/500Nodes/250Pods-40 250 127236420 ns/op BenchmarkSchedulingAntiAffinity/500Nodes/5000Pods-40 250 478661925 ns/op PASS ok k8s.io/kubernetes/test/integration/scheduler_perf 354.008s ``` **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes # **Special notes for your reviewer**: **Release note**: ```release-note NONE ``` |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
