### Other (Cleanup or Flake)

* Resolves bottleneck in internal API server communication that can cause increased goroutines and degrade API Server performance ([#80465](https://github.com/kubernetes/kubernetes/pull/80465), [@answer1991](https://github.com/answer1991))
* Update to go 1.12.10 ([#83139](https://github.com/kubernetes/kubernetes/pull/83139), [@cblecker](https://github.com/cblecker))

Özellikle, (diğer birçok araç arasında) Uvicorn, Starlette ve FastAPI'ın birlikte karşılaştırıldığını görebilirsiniz.

Aracın çözdüğü problem ne kadar basitse, performansı o kadar iyi olacaktır. Ancak kıyaslamaların çoğu, aracın sağladığı ek özellikleri test etmez.

Hiyerarşi şöyledir:

* **Uvicorn**: bir ASGI sunucusu
    * **Starlette**: (Uvicorn'u kullanır) bir web mikroframeworkü

		// We save a lot of calls over the network.

		// This happens repeatedly for all objects that are created concurrently() avoiding this

		// Spark based s3a committers are a  big enough use-case to have this optimization.

		// A sample code to see the improvements is as follows, this sample code is

### API Change

- Kubernetes 1.23 is now built with go1.19.4. To match behavior of previous Kubernetes 1.23 patch releases:
  - `kube-apiserver` defaults the GOGC setting to 63, to approximate go1.17 garbage collection memory performance in heavily loaded API servers
