Kubernetes delay pod-to-pod

Rafael Lenzi 1

I'm using a loadbalancer to receive the tags that I'm sending to mqtt, they arrive with a normal operation. However, when mqtt sends these tags received to the next containner, there is a delay of 1 minute between each process, which in my local environment happens in seconds. I would like to understand why the connection is so slow between pods.

I changed the service call that was '.default.svc.cluster.local' to the service's cluster ip but I didn't get a delay difference.

Hello @Rafael Lenzi ,
Thanks for reaching out to Microsoft QnA.
Have you tried capturing the network traffic and analyzing it?
I was trying to see what are the things we can do here do understand the cause behind this issue and I came across this blog here which might be helpful and relevant in this case - [pod-to-pod-network-delays-in-aks1.

Let me know if this is useful?

I had already captured the network traffic and I did what this blog suggests, but even so the delay always occurs after a continuous traffic (from the second message onwards)

Oh I see. This will require deeper investigation and log analysis. For this issue, I would recommend you to open a Azure support request with the Microsoft Support Team. If you do not have a support plan enabled for your subscription, please do reach out to me, and I can help enable a one-time free support for you. Thank you.

I would like it to open, I don't have it in my package. How do I contact you?
