Nimbostratuskubernetes ingres-nginx config change -> slow response time
Hi,
We find in two kubernetes clusters that any ingress nginx config changes are made (new backend, log modify...), the result is that the the proxy response time will be bad, slow, as long as we do not delete the pods. After restarting the ingress-nginx-controller pods everything is ok.
ingress-nginx-4.0.17
k8s: v1.21.6+2.el7
Idea?

There are a lot of of articles about tracing the traffic in nginx:
https://www.nginx.com/blog/application-tracing-nginx-plus/
https://www.nginx.com/blog/opentracing-nginx-plus/
https://docs.nginx.com/nginx-ingress-controller/troubleshooting/troubleshoot-ingress-controller/
Also you can check the release notes for known issues and fixes and better run the latest nginx version:
https://docs.nginx.com/nginx-ingress-controller/releases/#nginx-ingress-controller-222
Probably a silly question, but have you checked the logs of the ingress pods?
Also, have you checked any performance graphs in Prometheus to check for ie. CPU throttling?- Nikoolayy1
