Pods talking to external oracle database

Hi Guys,

We have deployed Istio with Istio Ingress controller as well as ngnix ingress controller in our AKS. We have deployed same application in two different namespaces. Application from pod talks to Oracle database present in the VM outside the cluster. We tested one scenario which is fetching just 15 records from the database. With ngnix ingress it is taking around few milliseconds to few seconds BUT with istio ingress it is taking more then 2 minutes (yes, you read it correct!!)…We are trying to understand why this huge delay! We have not setup it to go through Istio egress and no serviceentry is defined. It is just proxy in pod trying to get hold of data from Oracle. Nothing major found in the logs…

Any idea!!
